The best years of your life are the ones in which you decide your problems are your own. You don''t blame them on your mother, the ecology, or the President. You realize that you control your own destiny
In life, don’t expect anything from anyone.
Because expectation, when not fulfilled, gives you pain.
When you get something without expecting it,
It gives you pleasure.
Keep doing your part
And leave the rest to God.
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.
