It's always too early to quit.
Things do not happen. Things are made to happen.
The secret of getting ahead is getting started.
What you do today can improve all your tomorrows.
Either you run the day or the day runs you.
Quality is not an act, it is a habit.
Who seeks shall find.
Always desire to learn something useful.
Leap, and the net will appear.
Know or listen to those who know.
Greatness, in the last analysis, is largely bravery - courage in escaping from old ideas and old standards and respectable ways of doing things.
