The happiness of your life depends upon the quality of your thoughts.

I am an old man and have had many worries, but most have never come to pass.

Consider how many do not even know your name, and how many will soon forget it, and how those who now praise you will presently blame you.

I have often wondered how it is that every man loves himself more than all the rest of men, but yet sets less value on his own opinions of himself than on the opinions of others.

It's time you realized that you have something in you more powerful and miraculous than the things that affect you and make you dance like a puppet.

Leave other people's mistakes where they lie.

You need to be prepared for firm decisions and action, without losing gentleness towards those who obstruct or abuse you. It's as great a weakness to be angry with them as it is to abandon your plan of action and give up through fear.
