What a life! You get to spend all day, every day, on tennis courts during important tournaments and Grand Slam events. Yeah, you're just the ball boy, but someday….

You were never quite good enough to make the Pro Tour, but at least you still get to keep the game in your life, giving lessons at the Y for $15.00 an hour. You're pretty sure Pete Sampras will never have to resort to a gig like this.

You're on the Tour, but you're ranked 300-something in the world. You get to do what you love…but unfortunately, that doesn't include things like eating at nice restaurants or being able to send your family Christmas presents. In short—your butt is broke.

You're ranked in the top fifty of the WTA Tour. Once in a while you flirt with a Grand Slam title and collect a very nice payday; at other times, you collect a small check and move on. But at least you're out there, grinding it and making a nice living.

You're ranked #1 in the world on the ATP Tour. You just won the Australian Open, the only Slam you didn't yet have on your résumé. Top of the world, Ma.
