Mystic isn't wrong, but you can learn a lot by being around aviation and you can make a lot of contacts too. After all, life is all about being in the right place at the right time.
An extension of Mystic's logic though is "Why become a pilot?" Why not get some great paying job in computers, buy your own aircraft and fly whenever you want?
Perhaps a happy medium would be to do it and keep your eyes open. You'll know if you're being exploited.
