Strength of mind rests in sobriety for this keeps your reason unclouded by passion.

Keep your fears to yourself, but share your courage with others.

We suffer more often in imagination than in reality.

Faced with what is right, to leave it undone shows a lack of courage.

Courage is a mean with regard to fear and confidence.

There is a stubbornness about me that never can bear to be frightened at the will of others. My courage always rises with every attempt to intimidate me.

A truly strong person does not need the approval of others any more than a lion needs the approval of sheep.

We want deeper sincerity of motive, a greater courage in speech and earnestness in action.

There are two ways of exerting one's strength: one is pushing down, the other is pulling up.

What does not kill me makes me stronger.
