A wise man who stands firm is a statesman, a foolish man who stands firm is a catastrophe.
Firmness of purpose is one of the most necessary sinews of character, and one of the best instruments of success. Without it genius wastes its efforts in a maze of inconsistencies.
It is only persons of firmness that can have real gentleness. Those who appear gentle are, in general, only a weak character, which easily changes into asperity.
Real firmness is good for anything; strut is good for nothing.
Steadfastness is a noble quality, but unguided by knowledge or humility it becomes rashness or obstinacy.
The greatest firmness is the greatest mercy.
The purpose firm is equal to the deed.
