I would work for a year and save every penny (well except for the like 50k I would spend to live on plus mortgage that year).
Then at the end of the year, I would use the money to start a really shady strip club that everybody knows if you are willing to pay enough, you can get anything you want. This way I could have my pick of the hottest strippers in the place. I could play favorites to get them vying for my favor.
Then after the strippers had made me enough money, I would sell the business to fund my dream of starting a youth track club in inner city detroit, revitalizing the neighborhood and starting the second american running revolution.
I would be lauded as a hero in the running community and Mary Cain would want to shlog my knob. Of course, she would probably be about 35 by then, so I probably wouldn't let her, because there would be a new 18 year old super fast runner by then that I would choose as my prize instead.
Unfortunately, this would probably land me in the tabloids, because I would be famous and probably married after accidentally knocking up one of the aforementioned strippers. But then I would be vindicated when I get a paternity test and prove the brat isn't even mine. After the divorce, I would win back the hearts and minds of the public by adopting the stripper spawn as my own child.
But I would be broke at this point, so he would have to go to community college before transferring to a state school, but hey, it is better than his mother ever would have done for him.
