Brave hearts do not back down back off.
It is no weakness for the wisest man to learn when he is wrong.
Success is the reward for toil.
Let men be wise by instinct if they can, but when this fails be wise by good advice.
The greatest griefs are those we cause ourselves.
Do not believe that you alone can be right.The man who thinks that,The man who maintains that only he has the powerTo reason correctly, the gift to speak, the soul-A man like that, when you know him, turns out empty.
