For something,we can't understand when we are young but by the time we understand,we are no longer young. 有些事情，当我们年轻的时候无法懂得，当我们懂得的时候已不再年轻。
Ability may get you to the top, but it takes character to keep you there.
Count your age by friends, not years. Count your life by smiles, not tears. 衡量自己年不年轻，看朋友，而不是看年纪。 评价自己过得好不好，看笑容，而不是看眼泪。
Don’t let the past steal your present. 别让过去悄悄偷走了你的当下。
