If you've got a talent, protect it.
Wherever you are - be all there.
It's always too early to quit.
Either you run the day or the day runs you.
Well done is better than well said.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
Know or listen to those who know.
To know oneself, one should assert oneself.
Always desire to learn something useful.
Don't be afraid to fail. Don't waste energy trying to cover up failure. Learn from your failures and go on to the next challenge. It's OK to fail. If you're not failing, you're not growing.
