Man often becomes what he believes himself to be. If I keep on saying to myself that I cannot do a certain thing, it is possible that I may end by really becoming incapable of doing it. On the contrary, if I have the belief that I can do it, I shall surely acquire the capacity to do it even if I may not have it at the beginning.
Live as if you were to die tomorrow. Learn as if you were to live forever.
An eye for an eye only ends up making the whole world blind.
Strength does not come from physical capacity. It comes from indomitable will.
Non-violence, which is the quality of the heart, cannot come by an appeal to the brain.
