It's always too early to quit.
Leap, and the net will appear.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
The wise does at once what the fool does at last.
Things do not happen. Things are made to happen.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
Without hard work, nothing grows but weeds.
Know or listen to those who know.
Never follow somebody else's path it doesn't work the same way twice for anyone... the path follows you and rolls up behind you as you walk, forcing the next person to find their own way.
