Any person capable of angering you becomes your master; he can anger you only when you permit yourself to be disturbed by him.

It's not what happens to you, but how you react to it that matters.

God has entrusted me with myself. No man is free who is not master of himself. A man should so live that his happiness shall depend as little as possible on external things. The world turns aside to let any man pass who knows where he is going.

He is a wise man who does not grieve for the things which he has not, but rejoices for those which he has.

If anyone is unhappy, remember that his unhappiness is his own fault... Nothing else is the cause of anxiety or loss of tranquility except our own opinion.

What is death? A scary mask. Take it off-see, it doesn't bite.

We should do everything both cautiously and confidently at the same time.
