To enjoy freedom we have to control ourselves.

如果你没有失败，说明你没有突破极限；如果你没有突破极限，你就没有发挥出最大潜力。

Freedom is not merely the opportunity to do as one pleases; neither is it merely the opportunity to choose between set alternatives. Freedom is, first of all, the chance to formulate the available choices, to argue over them - and then, the opportunity to choose.
