Go for it, but don't tie yourself to just the 737. There are plenty of good airplanes out there to sample.
You can learn a lot from listening to other pilots at the airport, mistakes they have made as well as just some fun stories.
Search through some of the old threads here, plenty of questions have been asked just on this website alone.

I agree. The more you hang around the airport and more you talk to pilots and listen to stories, the more you get addicted. That's what happened to me, and now I can turn almost everything in life into something aviation related. I am unable to fly again until I finish school, but I still run to the window when I hear a plane go over head, and spend way to much time on Flightaware at work.
Good luck, I wish you the best.
