I got quite a few hours of instruction as a teenager and I loved it. Too may distractions got in the way though (i.e: girls, cars and girls in my car, etc.) and I never went much further. My goal within the next few years is to do my ground school and log enough flight time to finally become a licensed pilot 20-25 years later.

If you have an opportunity and think you can pull it off, jump on it. If you let too many things get in the way, quite a bit of time can go by.
