It's always too early to quit.
Know or listen to those who know.
Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
Do not weep do not wax indignant. Understand.
If you've got a talent, protect it.
What you do today can improve all your tomorrows.
After a storm comes a calm.
Be kind whenever possible. It is always possible.
Always desire to learn something useful.
I've just finished reading a book about the brilliant Margaret Rutherford. She wasn't a beauty, but inside she was absolutely blazing and passionate about her work. She's one of those life-affirming characters.
