    A buld-it-yourself solar still（蒸馏器） is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the U.S. Department of Agriculture, it's an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it's all but impossible to find natural substitutes. The only components required, though, are a 5'  5' sheet of clear or slightly milky plastic, six feet of plastic tube, and a container— perhaps just a drinking cup — to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.

    To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher's  productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up — and out — the side of the hole.

    Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet's center down with a rock. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.

    The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won't have to break down the still every time you need a drink.

    Sometimes when I'm flying from one speaking engagement to another, I find myself sitting next to someone who's quite talkative. This is often a pleasant experience for me because I'm a people-watcher. I learn so much by watching and listening to the people I meet and see every day. I've heard stories of sadness and others of delight, fear and joy, and others that would rival those on “Oprah” and "Geraldo”.

    Sad to say，there are times when I'm sitting next to someone who just wants to vent(发泄） his temper or inflict(强加）his political views on an audience for 600 miles. It was one of those days. I settled in, as my seatmate began his speech on the terrible state of the world with the time worn, “You know, kids today are...” He went on and on, sharing vague notions of the terrible state of teens and young adults, based on watching the six o'clock news rather selectively.

    When I gratefully got off that plane and finally made it to my hotel in Indianapolis, I bought the local paper and went to have dinner in the hotel. There, on an inside page, was an article I believe ought to have been the front-page headline news.

In a little Indiana town, there was a 15-year-old boy with a brain tumor. He was undergoing radiation and chemotherapy(化疗）treatments，As a result of those treatments, he had lost all of his hair. I don't know about you, but I remember how I would have felt about that at his age —I would have felt awkward and ashamed.

    This young man's classmates willingly came to the rescue: all the boys in his grade asked their mothers if they could shave their heads so that Brian wouldn't be the only bald boy in the high school. There, on that page was a photograph of a mother shaving all of her sons' hair with the family looking on approvingly. And in the background, a group of similar bald young men.

    No, I don't despair about kids today.

    My friend Kathy and I were going to Colorado Springs for holiday. The only problem was, I didn't have any luggage to pack my belongings in.

    My friend Debbie offered to lend me a suitcase that belonged to her father, who had passed away long ago. “I don't know if you'll want to use it,” she said so gently, “it's very old, worn out, and such an ugly yellow color." I was so touched by her offer to lend something that belonged to her father, but I was also concerned about the possibility of it being damaged or lost. She insisted that I take it. So with the suitcase safely in hand, I boarded the train with Kathy.

    We spent two days and one night on the train, sleeping in our seats. As we slept, we were awakened at times, by the noises of the train pulling in and out of the stations.

    The next morning we eagerly awaited the announcement: Next stop, Colorado Springs. But suddenly, there came another announcement over the loud speaker. “During one of the overnight stops, many pieces of luggage were mistakenly removed from the train and left at the wrong location.”

    Kathy and I just looked at each other, as I felt the disappointment swell. Could my worst fear be coming true, was Debbie's suitcase lost?

    Just then two train conductors passed our seats. One of them jokingly said to the other, “Did you ever see such an old, ugly, brighter yellow, piece of luggage in all of your life?”

    Before the other conductor could answer, I screamed, “YES, MY SUITCASE MADE IT!”

    The two conductors stopped in their tracks! and, very red in the face, couldn't seem to apologize enough for having insulted my suitcase.

    When I returned it, I couldn't wait to get the suitcase back into Debbie's safe hands. She asked, “Did everything go well on the trip?” Somehow. I just couldn't resist telling her what had happened. She laughed heartily.

    When I recall the golden suitcase, Fm reminded, that like the suitcase, we can see ourselves as too old, useless, worn out, and of little value. Or, we can take a closer look and realize that we are one of God's most valued creations -- unique, and holding inside our most valuable possessions -- that of love, faith, hope, and wisdom.

    Stained glass (彩色玻璃) artists create different designs by making cuts on the glass to “score” it and then breaking off the pattern that they want to use in the finished product. The most difficult cut in stained glass is called an inside cut. Basically, it's a curved (弯曲的) line where you throw away the part inside of the curve. The problem with inside cuts is that the edges of the curve tend to break off when the pieces of scored glass are broken apart.

    As the artist talked about inside cuts, he said, “The glass will break into pieces if you try to cut too much off at once. The best way to do an inside cut is to slice off smaller curves piece-by-piece. In fact, it's not just the best way to do it, but it's the only way to do it.”

    How many times do you try to make a big change and cut the entire piece at once? We convince ourselves that we can do this all the time. We'll commit to transforming our diet overnight or we get inspired to launch a business in a weekend or we finally get motivated to work out and push ourselves to the edge of burning out.

    Why not approach your goals and dreams like a stained glass artist? Starting by slicing a shallow curve and breaking a small piece off, you cut a slightly deeper curve and break that off until you have your full inside cut. By slowly cutting deeper and deeper curves, you prevent the glass from breaking as it changes shape.

    Of course, change isn't easy — no matter how you do it. Slow gains are boring, but if we keep making small improvements, then pretty soon we will end up with a beautiful masterpiece on our hands instead of a bunch of broken pieces.

    Rock climbing is not just for grown-ups. Your children can also enjoy this fun-filled activity as well as getting its advantages. Aside from its heart-health benefit, it is also known to increase their self-confidence and esteem(尊重). While it may not be an impromptu(即兴的) activity like running or biking, there are many climbing walls that are now available, especially with the development of fitness centers and camps.

    The great thing about having your kids join these activities is that it follows up on their natural quality. As you know, children are natural climbers. You can see them going up on trees or climbing tall ladders. With rock climbing, you can satisfy their urges to be a climber.

    What's more, it is fairly easy for the kids compared with adults. With a high strength-to-weight rate, they have less body weight to pull up, and they are more flexible(灵活的).

    It is also a low-impact workout that tests your children's endurance(耐性). It's easy on their joints(关节) as they burn energy during their ascent. In addition, climbing walls are like giant puzzles begging to be solved. Not only does it test the physical aspects of your children's development, but it also wakes their mental abilities.

    This exercise also helps develop your children's essential strength and flexibility. Kids are challenged physically as they pull, lift, stretch, and twist their way up. This activity also develops their eye-hand coordination(协调) as they perform their climb.

    Almost anyone can do it although it may vary in skill level, namely beginner, intermediate, or advanced. But despite its reputation as an extreme sport, children can do this. One does not need to be super-fit to join a rock climbing class. However, good technique is more necessary than strength when doing this sport.
