Always desire to learn something useful.
The wise does at once what the fool does at last.
Know or listen to those who know.
Never complain and never explain.
To know oneself, one should assert oneself.
Wherever you are - be all there.
Well done is better than well said.
It's always too early to quit.
After a storm comes a calm.
To be a good loser is to learn how to win.
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.
