Nope, it doesn't.
The first twenty years of your life is all fun, and games, but after that, you either going to do repetitive boring work nearly every day for the next 40 or so years, or live a lonely solitude life living on the dole.
When you get to 20, you might aswell just slit your own throat than live life.
I know this may sound harsh, or cruel, but it's the truth, life is only going to get harder. I'm not going to be pussyfooting around here, and saying that adult life is all sunshine, and rainbows because it isn't.
I would absolutely kill for another shot at my teens, and if i did i wouldn't waste the time away like i did.
