The only freedom which deserves the name is that of pursuing our own good in our own way， so long as we do not attempt to deprive others of theirs， or impede their efforts to obtain it.

I think goals should never be easy, they should force you to work, even if they are uncomfortable at the time.

和平时期流汗越多，战争时期流血越少。

Don't get involved in partial problems, but always take flight to where there is a free view over the whole single great problem, even if this view is still not a clear one.
