It is amazing how much can be accomplished if no one cares who gets the credit.
Never let your emotions overrule your head.
There is no pillow as soft as a clear conscience.
A player who makes a team great is better than a great player.
There is no great fun, satisfaction, or joy derived from doing something that's easy.
Being yourself; not acting. You therefore can function near your own level of competence. Satisfy you own expectations rather than those of others.
