Be more concerned with your character
than your reputation,
because your character is what you really are,
while your reputation
is merely what others think you are.
Give all options to the opponent, if you win its historical, if you fight and loose- he is definite to loose next time, if you loose-you can enjoy his happiness even.
"You are always a valuable, worthwhile human being, not because anybody says so, not because you''re successful, not because you make a lot of money, but because you decide to believe it and for no other reason."
When guilt rears its ugly head confront it,
discuss it and let it go. The past is over.
It is time to ask what can we do right,
not what did we do wrong.
Forgive yourself and move on.
