If you're going through hell, keep going.
Know or listen to those who know.
Things do not happen. Things are made to happen.
You never know what motivates you.
Be gentle to all and stern with yourself.
Never complain and never explain.
The dog that trots about finds a bone.
If you've got a talent, protect it.
Quality is not an act, it is a habit.
The secret of getting ahead is getting started.
If you always put limit on everything you do, physical or anything else. It will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.
