    If I were a boy again，I would try hard to know about myself.Then I would deal honestly with myself，to study up on my own weaknesses and strengths.I would begin early enough，before mistakes had time to become habits.
    If I were a boy again，I would never give up.There is nothing more valuable than a continued effort when the right thing needs to be done.
    If I were a boy again，I would try to look on the cheerful side of everything.Life is like a mirror，if you smile in front of it，it smiles back on you；if you frown （皺眉），you will be sure to get a similar look in return. "Inner sunshine warms not only the heart of the owner，but all who come in contact（聯(lián)系）with it. "
    If I were a boy again，I would build a habit of attention，and I would let nothing come between me and the subject at hand：an ice skater never tries to skate in two directions at a time.One of our great mistakes，while we are young，is that we do not focus（關注） strictly on what we are doing at the particular moment.It is easy to learn how to pay attention，if we begin early enough.
