If you know you can do it - if you can already chart every day in your future - then why bother? Choose to do something you have more trouble imagining. Take a chance.

Housework can't kill you, but why take a chance?

If you do not believe you can do it then you have no chance at all.

To change, to convert? Why bother?

My philosophy is, unless you're sick and need help, why bother?

Before you take your address, while you're still reading the putt, imagine the ball tracking on the line you've chosen and falling into the cup. If you don't believe you can make every putt, why bother trying?
