If You Want To Improve Be Content To Be Thought

I'd rather be an optimist and a fool than a pessimist and right.

Mistakes are, after all, the foundations of truth, and if a man does not know what a thing is, it is at least an increase in knowledge if he knows what it is not.

Pretend inferiority and encourage his arrogance.

Weakness of attitude becomes weakness of character.

Strive not to be a success, but rather to be of value.

If you make a mistake and do not correct it, this is called a mistake.
