If you want to own your own business for the "Glory" you will be in for a rude awakening. Not to mention  an empty wallet.
The real motivation for having your own business should come from the  idea that you have something to offer to the world that is not yet being expressed in a particular way. And furthermore, you may have the "IT" idea, but that doesn't mean you are the person to execute it. Know your role, and play it accordingly. Life will run more efficiently this way.
