     It's easier to go down the hill than to climb up the hill, so it is easier to fall into bad habits (习惯) than
into good ones.
     Bad habits do not come suddenly. They come little by little without one being aware of (意识到) their
danger. School boys first pick up little bad habits in the school and on the street. When they can't write
their lessons, they copy from their schoolmates. If they see bigger boys smoking, they also want to learn
to smoke. If they see their friends gambling (赌博), they want to gamble. When they get bigger, the habits
become stronger and stronger, so that they can no longer get rid of (摆脱, 除掉) them. From copying,
they learn to steal, from gambling, they learn to cheat (欺骗). At last they become distrusted (不信任) by
everybody. How necessary it is that we get rid of the bad habits in the beginning.
