There are many things you cannot control, but you can control the only things that really matter: your mind and your attitude. External forces have very little to do with success. Those who program themselves for success find a way to succeed even in the most difficult of circumstances. Solutions to most problems come from one source and one source alone: yourself. Living life to the fullest is a lot like shooting the rapids in a rubber raft. Once you’ve made the commitment, it’s difficult to change your mind, turn around, and paddle upstream to placid waters. But it’s the excitement and adventure that make it all worthwhile. If you never make the attempt, you may never know the depths of despair, but neither will you experience the exhilaration of success.
