The way I see it is you have two choices in life; you can be grateful for everything life has given you or you can be resentful for everything life has done to you. Your degree of happiness is directly proportional to the conviction of your choice
I am only one,
But still I am one.
I cannot do everything,
But still I can do something;
And because I cannot do everything
I will not refuse to do the something that I can do.
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.
Life is a paradox whatever you want - you dont get,
Whatever you get - you don''t enjoy,
Whatever you enjoy - is not permanent and
Whatever is permanent - is boring
