Shrunk Down

Did you ever think about going back in time and fixing your past mistakes? I sure have, but in this scenario, you won't be traveling back in time. One lazy and fateful night, you wonder if you can return back and fix your life from the past mistakes you did from your youth. Unexpectedly, that comes true! Well... Only the youth part. You're now a minor with a thirty-six year old brain, how can you change your life for the better? Or will you become a street rat because you can't pay rent... since you're a minor and can't get a job. (Please don't be weird about this. I beg.)
