You never know what motivates you.
Be thine own palace, or the world's thy jail.
By failing to prepare, you are preparing to fail.
Either you run the day or the day runs you.
Who seeks shall find.
Know or listen to those who know.
The dog that trots about finds a bone.
If you've got a talent, protect it.
I can, therefore I am.
Things do not happen. Things are made to happen.
