“The first and best of victories for a man is to conquerhimself; to be conquered by himself is, of all things, the most shameful,” saysPlato. Self-control is at the root of all the advantages. Let a man give in tohis impulses (冲动) andfeelings, and from that moment he gives up his moral freedom.

A single angry word has lost many friends. When Socrates foundin himself any temper or anger, he would check it by speaking low in order tocontrol himself. If you are conscious of being angry, keep your mouth shut sothat you can hold back rising anger. Many a person has dropped dead in greatanger. Fits of anger bring fits of disease. “Whoever the gods would destroy,they first make them mad.” “Keep cool,” says Webster, “anger is notargument.” “Be calm in arguing,” says George Herbert, “for fierceness (狂怒) makes error a fault.”

To be angry with a weak man is to prove that you are not strongyourself. “Anger,” says Pythagoras, “begins with foolishness and ends withregret.” You must measure the strength of a man by the power of the feelings heconquers, not by the power of those which conquer him.

Self-control is man's last and greatest victory.

If a man lacks self-control he seems to lack everything. Withoutit he can have no patience, no power to govern himself; he can have noself-confidence, for he will always be controlled by his strongest feeling. Ifhe lacks self-control, the very backbone and nerve of character are lackingtoo.

    Group exercise is one of the most effective ways to improve physical fitness and sustain a healthy lifestyle.Group exercise is challenging, yet fun and empowering! Of course everyone knows that exercise is good for the body.However, studies have shown that when exercise is performed in groups, it's not only great for improving physical health but for psychological health. It's an opportunity to be social, release endorphins  , and improve your strength. Additionally, group exercise creates a community feel and the shared common goal motivates participants to work hard. The instrumental support of taking on a fitness journey with others proves more effective than going to the gym alone.

    Another beneficial aspect of group exercise is the informational support participants receive from the instructor.Many people fear the gym because they feel lost and don't want to embarrass themselves. If you feel you can relate, then group training is an even better option for you. It's a great opportunity to learn more about fitness through the clear instruction and supervision of a fitness instructor. If you're tired of wandering around the gym wasting time and becoming bored, !you can attend an upbeat group fitness class that'll keep your workout on track. Don't let fitness frighten you!

    If you're serious about wanting to live a healthy lifestyle, it's extremely important to surround yourself with people who'll provide you with the proper emotional support. I wouldn't scold anyone for deciding to party on weekends and in turn I wouldn't expect anyone to give offence to me for focusing on my health. Surround yourself with people who uplift, encourage and understand you! Make fitness even more fun by trying something new or any group fitness class, with a friend. Plan to go for a jog together. Then try a fun healthy restaurant or fresh juice bar! Fitness can be both fun and social!

    Surrounding yourself with people who'll provide you with respect support can be very beneficial while working towards reaching health and fitness goals. First, decide to do it for yourself and work towards staying positive. Then make sure the people you surround yourself with are supportive. Don't let negativity ruin your motivation.

    It is common and usual to see people freak out when they face challenges in their life. We all pass in different life problems and challenges. No one is free of life problems. Only a dead man faces no problem. As long as you are alive, challenges are everywhere.

    How do you face problems and challenges in your life? Problems and challenges are the building blocks of your personality. They make you who you are. Besides, whether what happened in your life builds or destructs you depends on how you look at it. If you take your problems as troubles, they will be troubles and may cause destruction. If you take them as constructive tools, you are going to be built up on them.

    Problems are everywhere. No one can avoid them. And they are good too. They open up a different look and opportunity if you are willing to see. When you face troubles, do not frustrate or freak out. Just cool yourself to think in a different direction. Think in a positive way. Every problem has its own good as well as bad sides. Focus on the good one. Look at the bright side.  Besides, there is always a good person, perhaps your mom or dad, or one of your friends, right beside you who can turn everything into your best if you are willing to turn to them. No matter what happens, they will be there to help you. Trust them and they will never let you down. All you need to know is that you are loved wherever you are.

    ARCHAEOLOGISTS (考古学家) GUIDED BY laser images of a remote region of northern Guatemala have discovered 20-foot-high walls, watchtowers, and other evidence that ancient Maya societies had been annoyed by warfare threat over many years. The finds have upended long-established impressions of a civilization that it tamed the jungle and built thriving cities, then declined and disappeared quietly beneath the dense tropical forest.

    Among the most surprising discoveries was a large stone complex now called La Cuemavilla. Built on a steep ridge, the heavily fortified site included high walls. Moats which serves as the largest defensive system ever discovered in the region.

    This was surprising says an archaeologist, because we had a tendency to romanticize Maya warfare as something that was largely ritualized. But the fortifications were seeing suggest an elevated level of antagonism over centuries. Rulers were so deeply alarmed that they felt the need to invest in all these hilltop fortifications. There is an almost visible sense of fear in this landscape.

    All these findings owe credit to PACUNAM LIDAR Initiative, a laser survey of some 800 square miles of the Maya Biosphere Reserve in northern Guatemala. Using revolutionary Laser technology, the survey revealed the long-hidden ruins of a sprawling pre-Columbian civilization that was far more complex and interconnected than most Maya specialists had supposed.

    Guided by the new Laser treasure maps, the LIDAR team deployed through the jungle over the past year to conduct hands-on investigations of more than a dozen of the most promising sites-most of which would have been imperceptible without LIDAR.

    "You could walk over the top of a major ruin and miss it, "says an archaeologist who's part of the PACUNA project. But LIDAR picks up the patterns and makes the features pop out with surprising clarity.

    Three-dimensional maps generated by the survey yielded surprises even at Tikal, the largest and most extensively explored archaeological site in Guatemala. The ancient city was at least four times bigger than previously thought, and surrounded by a massive ditch and fortified base stretching for miles.

    Archaeologists stress that LIDAR, for all its utility, will never see below the ground or yield direct dates of occupation. "We still need to dig and hack our way through the jungle, but now we have a very accurate map to guide us."

    Years ago, I volunteered at a homeless shelter in Los Angeles, handing out food. Once I got talking with Albert, a tall and skinny young guy in line. He said he liked my socks. "Want to see mine?" he joked, lifting his leg. He was barefoot. I felt a sinking feeling in my stomach.

    The next day, after work, I stopped at Ross and filled up my truck with socks. The following early morning, I drove over to Santa Monica's Palisades Park, which is a common destination for homeless people.

    I took one of the bags from my trunk. It was still dark out. I headed for a group of three men, standing around a tree, probably using it as a windbreaker. Two were asleep under heavy blankets, and the third was digging through his collection. As I walked toward him, he watched me, perhaps questioning my motives. "I thought you guys might need some fresh new socks," I said, handing him a pair. He looked confused at first but took them and said, "Thank you." I gave him two more pairs for his friends.

    I moved on. An hour later, I had given out all the socks. Most people were sleeping, and I felt like Santa. I knew that when they wake up they would find a very meaningful present.

    That was nine years ago. Every week I'll hand out as many socks as I can. If I'm on vacation or on a business trip for more than a week, I bring a bag of socks with me and hand them out to the homeless on the streets in other states and countries.

    It's extremely satisfying to operate "under the radar(雷达)" to help make some people's lives a little bit easier. Part of me hopes to see Albert out there one of these days, but even if I don't, I like to think one of the pairs will find him.
