I can, therefore I am.

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

The most effective way to do it, is to do it.

Things do not happen. Things are made to happen.

Do not weep do not wax indignant. Understand.

Never complain and never explain.

You never know what motivates you.

By failing to prepare, you are preparing to fail.

Always desire to learn something useful.
