I play chess because even though I used to be very good at it when I was younger, I didn't know how to enjoy it. Now I know how to enjoy it, and forgot how to play as well as I used to when I was younger, so now I can actually enjoy getting better and better at it!
I'm now aspiring to reach GM level, no matter if it takes me 3 years or 30. Of course, I can't devote my whole life to chess, but I can take the philosophy from it and apply it to life, and continue to enjoy myself as I improve.
Update: I no longer care about getting a title, I just love this game.
