Quality is not an act, it is a habit.
Be thine own palace, or the world's thy jail.
After a storm comes a calm.
If you've got a talent, protect it.
You never know what motivates you.
Expect problems and eat them for breakfast.
Never complain and never explain.
The dog that trots about finds a bone.
The most effective way to do it, is to do it.
To know oneself, one should assert oneself.
But to me the bottom line is the more education you can give yourself, and the more preparation you can do, the less chance of failing.
