问题     A young boy was sitting in the back seat of the car eating an apple. He asked his father, "Why does my apple turn brown?" His father answered, "When the skin is removed, air reaches the flesh of the apple and causes oxidation(氧化)." This changes the apple’s molecular(分子的)structure and results in a brownish color." The boy asked, "Daddy, what are you talking about?"
    I know how that boy feels. Sometimes I want answers to some of those confusing problems that we all run up against, such as how to get through difficult times or what to do in a tough situation, I just want to get it right.
    The problem is that I don’t always have the answers I need. Nobody else seems to have them, either. So I blunder ahead and think that I’ll never get it "right".
    Often I didn’t know what to do. I often made poor choices, but I gradually improved. Then I realize that I don’ t have to always get it right. I don’ t have to always know what to do all the time. All I really need to do is try my best, learn from my mistakes and go on.
    Dr. Leo Buscaglia once said, "No one gets out of this world alive, so the time to live, learn, care, share, celebrate and love is now. That would be pretty hard to do when you’re waiting for all the answers first."
    So you got it wrong. You made a mistake. What should you do next? Forgive yourself and try again. You may not get out of this world alive, but you can get plenty of life out of this world if you’ re not too worried about always getting it right.
