Never lie; never cheat; never steal. Don't whine; don't complain; don't make excuses.
Losing does not make you a failure; it is when you blame someone for losing when you become a failure
Consideration for others brings many things.
Discipline of others isn't punishment. You discipline to help, to improve, to correct, to prevent, not to punish, humiliate, or retaliate.
The greatest failure of all is the failure to act when action is needed
Don't permit fear of failure to prevent effort.
