我最害怕的莫过于共和国分裂成两个大党，每个党都在其领导人的领导下，相互对立地制定措施。

韧性不在于避免失败，而在于学会每次跌倒后重新站起。

The statesman， who should attempt to direct private people in what manner they ought to employ their capitals， would not only load himself with a most unnecessary attention but assume an authority which could safely be trusted， not only to no single person， but to no council or senate whatever， and which would nowhere be so dangerous as in the hands of a man who had folly and presumption enough to fancy himself fit to exercise it.

Your brain is more powerful than you think; the key is learning how to activate it.

Prejudices are what fools use for reason.
