Compared to the whole development of history, your life could be like a candle which is lit and then blown out immediately. In other words, life is short —very short. Missing any of the joys life offers is terrible.

So don’t let fears conquer your short and valuable life. If your life is being controlled by your fears, you are most certainly cheating yourself. Courage is the mental (精神上的) muscle that conquers fear. Like all muscles, the more you use it, the stronger it will become. Courage is not something you are born with. That is to say, it must be developed. It has been said that if you face the thing you fear bravely, your fear will leave you.

For years I believed that courageous people had no fear. I was wrong. Eddie Richen Bacher put it very well when he said, "There is no courage without fear." We all have fears; however, not everyone gives in to their fears easily.

There is, very likely, something you have wanted to do for years —move to another city, start your own business, apply for a better position, or go wherever you like. Whatever it is, you should do it. Remember, life is not a practice run. This is it. A little courage leads to more.

Observe those poor people who have no courage. They only tiptoe (蹑手蹑脚地走) through life, hoping they can make it safely to death. You and I never meant to live that way. Learn to live the way you like by no longer living as you dislike. Make good use of your day and have courage. That’s life!
