The thread on spin and power by the pros had some discussion on what ranking had to be achieved in order to make a living. That got me to thinking. People make a living in tennis in ways other than being on the pro tour, e.g., via working for a tennis association, coaching tennis, in the pros or at college tennis, tennis instruction, running tennis camps, owning and running a tennis shop, being a club, resort, or camp pro, stringing tennis racquets, etc. Here's my question. Does a stint on the pro tour enhance the chances of making a living in tennis via these other avenues? I can imagine it does. Especially if one has been ranked say in the top 100 in your home country say, or if one has played at Wimbledon, or at the US Open, in either singles or doubles. Next question. Could making a living from tennis in these other ways be more fun and/or earn you more money than the average career of an average college graduate? If so, maybe it's not so dumb to for someone with some tennis talent to try the pro tour rather than college. Anybody know anything specific about these questions (like how much can you make teaching tennis, or being a pro at a resort)? How about a guess?
