"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."
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
