If you think you are beaten, you are. If you think you dare not, you don't. If you'd like to win but think you can't it's almost certain you won't. Life's battles don't always go to the stronger or faster man, but sooner or later, the man who wins is the man who thinks he can. A happy person is not a person with a certain set of circumstances, but rather a person with a certain set of attitudes. I may not be able to change the world I see around me, but I can change the way I see the world within me.
