"You can't go back and change the beginning, but you can start where you are and change the ending."
你无法回到过去改变开头，但你可以从现在开始改变结局。
The mind is not a passive recipient of sensory information but an active participant in the process of perception.
The only way to achieve the impossible is to believe it is possible.
如果你从未跌倒过，那么你也就从未努力过。
