Never complain and never explain.
Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
To be a good loser is to learn how to win.
Be kind whenever possible. It is always possible.
Expect problems and eat them for breakfast.
Quality is not an act, it is a habit.
The dog that trots about finds a bone.
Know or listen to those who know.
I didn't go to university. Didn't even finish A-levels. But I have sympathy for those who did.
Never trust any complicated cocktail that remainds perfectly clear until the last ingredient goes in, and then immediately clouds.
