Never give up, for that is just the place and time that the tide will turn.
The only person you should try to be better than, is the person you were yesterday.
One way to keep momentum going is to have constantly greater goals.
You can never cross the ocean until you have the courage to lose sight of the shore.
You must expect great things of yourself before you can do them.
Your present circumstances don't determine where you can go; they merely determine where you start.
Always make a total effort, even when the odds are against you.
The best way to predict the future is to create it.
The only thing standing between you and your goal is the bullshit story you keep telling yourself as to why you can't achieve it.
Of course motivation is not permanent. But then, neither is bathing; but it is something you should do on a regular basis.
