下的学Don't wait. The time will never be just right.读懂的生Wake up with determination. Go to bed with satisfaction.前古It’s going to be hard, but hard does not mean impossible.

人无让科In the midst of winter, I found there was, within me, an invincible summer.意留Push yourself, because no one else is going to do it for you.
