What you do today can improve all your tomorrows.

The secret of getting ahead is getting started.
Be thine own palace, or the world's thy jail.
Go for it now. The future is promised to no one.

Well done is better than well said.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
