It's always too early to quit.
Know or listen to those who know.
Who seeks shall find.
Quality is not an act, it is a habit.
Expect problems and eat them for breakfast.
Wherever you are - be all there.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
Go for it now. The future is promised to no one.
A man always has two reasons for doing anything: a good reason and the real reason.
Go as far as you can see when you get there, you'll be able to see farther.
