If I were a boy again, I would practice perseverance more often, and never give up a thing because it was inconvenient. If we want light, we must conquer darkness. Perseverance can sometimes equal genius in its results. "There are only two creatures," says a proverb, "Who can surmount the pyramids - the eagle and the snail." 　 If I were a boy again, I would school myself into a habit of attention; I would let nothing come between me and the subject in hand. I would remember that a good skater never tries to skate in two directions at once. The habit of attention becomes part of our life, if we begin early enough. I often hear grown up people say, "I could not fix my attention on the sermon or book, although I wished to do so", and the reason is, the habit was not formed in youth. 　 If I were to live my life over again, I would pay more attention to the cultivation of the memory.
