Wow. Talk about how tough it is to be a tennis pro! You'd make more working at McDonald's and at least after a few years you might make assistant manager. The public only really sees the top handful of players who make money while the rest toil in obscure poverty.
In Andy's "most successful weekend" (quote from July 12 blog), he finished second in Open singles and won the Open men's doubles in the Nike Championships. A well-sponsored large event. How much did the hours of playing net him? $660 for second in the singles and $360 ($720 per team) for the doubles victory. With all the travel, eating, etc. no wonder the poor guy has to stay at people's houses along the way just to try and scrape by. $1020 before expenses from your best weekend, how many other weekends were negative after expenses? He's certainly not saving any money? What do you do when you "retire" at 35 with no money and no experience for a real job - teach tennis private lessons I guess? This should be a good advertisement for stay in school, get a real job, and spend your time to "go pro" in your regular job - you'll have more $$, more success, and can play tennis for fun on the weekends too!
