C'mon, give the OP a break...
From his posts it sounds like he realizes that the chances of him getting an ATP point are slim at best. But if having that as a long-term goal is motiviation to get in better shape, practice harder, and play better, then why not? As long as he is not sacrificing other parts of his life (which it does not sound like), and as long as he can deal with the disappointment if it doesn't happen.
Reading the OPs first post, he's not looking for advice, suggestions, etc... he just wants to share the experience.
To the OP: Go for it man!!
