Never complain and never explain.

Things do not happen. Things are made to happen.

The wise does at once what the fool does at last.

You never know what motivates you.

Be thine own palace, or the world's thy jail.

Problems are not stop signs, they are guidelines.

By failing to prepare, you are preparing to fail.

Expect problems and eat them for breakfast.

Do not weep do not wax indignant. Understand.
