Basically, you get out what you put in, BigCrate. Sure it'll be a change of pace for you, but think of how you'll feel once the dust has settled. You'll have a good base to build from, you'll be in great shape, you'll learn discipline, and IMO you'll have a feeling of "yes, I *did* it." Think of all the other yahoos in the world loafing their way up the Burger King ladder while you, on the other hand, will have valuable life experience. Sure, you can gain experience at BK... finding the best way to flip da burger, but when will you really need that?
I'm still in school, I sign up for advanced and more difficult classes to challenge myself. I see screw offs and knuckleheads simply gliding through the years on the bare minimum.. skipping most classes, screwing around with a care free attitude. Some teachers say "oh look, there goes your future employees."
My problem used to be I thought too much. Had to think everything through twice before I even attempted to make a move. I turned myself around.. I feel I take many risks... Taking the dive, jumping into the unknown, just going for experience really pays off. I honestly can't wait for my opportunity. Whats the worst that could happen? So you end up not liking it? What could you lose? Some time out of your life in exchange for mounds of knowledge and experience? My philosophy has been to get a taste of everything you can, experience all you can experience, big or small, just be there. Then make your decision.
