I climbed Kilimanjaro with Lava Expeditions (探险队) during the rainy season.

    I flew to Nairobi in Kenya and spent several days there. At my hotel in Nairobi I met the rest of the group with whom I would spend the next week. We all travelled on the bus together for a 6-hour journey into Tanzania and then Arusha, a quiet town.

    After we arrived at our hotel in Arusha, we had dinner and a few drinks. Then we were introduced to more members including Taddeus Minja, the main guide, who was very experienced — climbing Kilimanjaro runs through the generations (代) of his family.

    The next day the Lava Expeditions members checked if we had the correct and enough clothing for our expedition on Kilimanjaro. Only one person needed to bring more clothes.

    After that we set off, walking in the rain through the beauty of the rainforest, all the way to the first camp. I was happy the next few days as the view was so wonderful and changed every day. I suffered a little during the trip and I felt so tired. But the members of Lava Expeditions provided me with lots of encouragement, which was one of the best memories. Finally we reached the top of Kilimanjaro in bright blue skies.

I felt excited about climbing Kilimanjaro and the feeling didn't change during my trip. Lava Expeditions looked after me so well that I was deeply thankful for their help.

    On a cool morning, Wilson Kasaine heads out along a dirt path in southern Kenya. His calmness makes it easy to forget that he's tracking one of the most dangerous animals in the world. Kasaine is tracking lions—especially one lion called Marti, who is the real-life Lion King of Selenkay Conservancy.

    Tracking lions on foot may sound like a death wish, but Kasaine has been doing it for most of his life. Born into a traditional Maasai family he quickly grew to understand the beauty and danger of wildlife. Living with big wild animals forces him to develop a good sense of where they have been and where they may be going. During his 12-kilometer walks to and from school, he learned how to tell the paw prints (爪印)of a lion from those of other animals.

    Growing up, Kasaine knew that improving his tracking abilities would help him avoid surprise meetings with dangerous animals. For many Maasai, tracking is mainly a matter of self-protection. But Kasaine is tracking lions to meet them and to protect them. He leads a small group of wide-eyed tourists over the red sandy path, searching for the lion that has left upon it his prints.

Each year, thousands of tourists crowd Kenya's national parks to try to have a look at the"big five”; elephants, rhinoceros, leopards, buffaloes and lions. The international draw of these animals matters a lot because the nation's economy is tied to the protection of its wildlife. If Kenya's wildlife disappears, so does its second-largest source of income.

    Wildlife protection efforts in Kenya meant marking off land exclusively(专门地)for animals. But it also meant that the people who had originally lived in the area were forced to leave their land and into smaller surrounding areas. They are also finding it increasingly hard to keep a traditional Maasai lifestyle. But people are glad that it really makes a difference to wildlife protection.

    It was dangerously cold. A few drivers slipping and sliding off the road and back on again had cut deep ruts（车辙）in the mud. And the ruts became frozen solid. The drum of our truck's aging engine worried us.

    Trees and bushes heavy with snow bent to form an icy tunnel. We inched along the scary route as Howard grasped the steering wheel（方向盘）tightly, trying to keep the truck in the ruts. We were now riding through a nightmare with no going back. I kept praying the truck would not quit.

    However, the engine's coughing grew worse. We came to a bumping stop. Hot tears ran down my face. We noticed a small house off in the distance. “I will go for help.” Howard's words ruined my common sense and panic took over. We would take the children — we would walk to that house together!

    But the snow was deep, and our two children, asleep in the cab, were too heavy to carry. My husband convinced me to let him go alone. If no one was home or they didn't answer the door, he would come back and we'd try to hike out to a main road. For now, it was safer in the truck. I wish I could say I have faith, but when he walked away, I was mad at the world.

    It seemed as if hours had passed before I heard a familiar voice and a kind laugh of another man as they approached in the snow. The older fellow invited us to go up to the house where his wife was waiting. Two wide-awake kids moved across the seat, ready for adventure. Their voices and laughter carried in the cold night air. When we finally got close, a cheerful woman opened the door. Warm air and the smell of hot buttered popcorn and chocolate drew us in.

     Relieved, my prayers were heard!

    When I was a boy there were no smart phones, computers were something you saw on STAR TREK, and our television only got one channel clearly. Still, I was never bored. The fields, hills, and woodlands around my home were the perfect playgrounds whose adventures were only limited by my imagination. I can remember once hiking to a nearby lake and slowly walking around it. At the backside of it I was amazed to find an old, one lane, dirt road that I had never seen before. I immediately set out to travel it. It was full of muddy tire tracks and deep woods bordered it on both sides, but exploring it still seemed like a fine adventure.

    I walked on and on for what seemed like hours. I am sure my guardian angel was whispering in my ear to turn around and head back home but I was stubborn and even a bit stupid, so I walked on. The dirt road gave way to a gravel one and then a paved one, yet there was still neither a car nor a house in sight. My legs were getting tired. I noticed that the sun was starting to go down and I grew scared. I didn't want to end up trapped on this road in the dark of night, but I was sure it would be dark before I could make my way back to the lake again.

    I continued to walk on with the something growing inside of me. My heart was pounding and my legs were aching. I was almost in tears when I turned one last curve and saw something in the distance. It was a house that I recognized. My heart leapt up! I jumped up and down and laughed out loud. I knew the way home! It was still over a mile away but my legs felt like feathers and I hurried back to my house in no time. I walked in with a big smile on my face just in time for dinner. Then I ended my adventure with a good night's sleep.

    I often thought of that experience recently. Actually, in our life, all roads, no matter how they twist and turn, can lead us home again. They can lead us to our homes here on Earth. They can lead us to our homes in our hearts. May you always walk your path with love. May you always help your fellow travelers along the way. And may your roads always lead you Home again.

    Do you often feel that you aren't taking in as much of the joy around you as you could? I recently caught myself feeling this way, and based on a suggestion by John Horton, coauthor (合著者) of The Inner Game of Stress, I put myself on a 30-day life-appreciation course.

    The only assignment each day was to go outside and appreciate life.

    So I started by taking in the beauty around me. During the first few days, I was able to appreciate my surroundings, although it was an intellectual appreciation, not an emotional one.

    After the first week, it was more uncomfortable to lie in bed and think about things than it was to get up and see them for myself.

    If you often wake up feeling anxious or depressed, or if you don't look forward to each day, then you need to try this course for yourself.

    It's an inner workout that you can do anywhere. It may not change your life, but it will adjust your attitude, and that's pretty helpful in this crazy world.

    I have always believed in ending the day on a positive note by writing a word or two in a gratitude journal and saying something sweet to my wife about the day we shared.

    Now, I have a new morning habit. It hasn't changed my routine one bit, but it has changed the way I look at the world.

    Creating a new habit isn't about perfection – it's about getting what you want by creating a change in your behavior and thinking.

    So now, while I'm making my coffee in the morning, I'm also appreciating what I have.

    It's quick, fulfilling, and a much better way to start my day than looking at my phone or computer.

    And because of this, my attitude is better, as I've already begun my morning on a positive note rather than a problematic one.

    The idea here is that if you can appreciate your life, it actually changes the way you feel about it.

    Appreciation will give you more energy to live the way you would like to live.

    As a means of improving our mood, it's highly underrated (被低估的). The easy task of appreciating what we have simply makes life better.

    Attitudes toward new technologies often fall along generational lines. That is, generally, younger people tend to outnumber older people in face of a technological shift.

    It is not always the case, though. When you look at attitudes toward driverless cars, there doesn't seem to be a clear generational divide. The public overall disagree on whether they'd like to use a driverless car. In a study last year, of all people surveyed, 48 percent said they wanted to ride in one, while 50 percent did not.

    The fact that attitudes toward self-driving cars appear to be so steady across generations suggests how transformative the shift to driverless cars could be. Not everyone wants a driverless car now——and no one can get one yet ——but among those who are open to them, every age group is similarly engaged.

    When it comes to driverless cars, differences in attitude are obvious based on factors not related to age. College graduates, for example, are particularly interested in driverless cars compared with those who have less education: 59 percent of college graduates said they would like to use a driverless car compared with 38 percent of those with a high-school diploma or less.

    Where a person lives matters, too. More people who lived in cities and suburbs said they wanted to try driverless car than those who lived in rural areas.

    While there's reason to believe that interest in self-driving cars is going up, a person's age will have little to do with how self-driving cars can become mainstream. Once driverless cars are actually available for sale, the early adopters will be the people who can afford to buy them.
