To know oneself, one should assert oneself.
If you've got a talent, protect it.
It's always too early to quit.
Do not weep do not wax indignant. Understand.
Be kind whenever possible. It is always possible.
Know or listen to those who know.
The secret of getting ahead is getting started.
If you think you can do it, you can.
The wise does at once what the fool does at last.
Expect problems and eat them for breakfast.

Movies are not scripts - movies are films they're not books, they're not the theatre.
