Look, you have already made up your mind. Stop beating the dead horse. Everyone here has given you stellar advice. If you truly think you are going to relocate to a new state with no higher education and get a high-paying job and a sweet apartment, you are sorely mistaken.
I am going to tell you again what Bill told you. YES YOU WILL BE BROKE. Whether "broke" to you means living on mac and cheese or PBJ and working 2 low-paying jobs - or living on the street, you WILL BE BROKE and POOR.
You can trust me. I haven't lived at home since I was 16. YOU WILL BE BROKE AND POOR. Believe it. I didn't have the luxury as you do of being able to run home to Mommy and Daddy if it didn't work out. I am sure this fact has the most bearing on your decision and your cavalier attitude.
Also, whoever told you Florida is not in the bottom percentile on wages and has a nice low cost of living is a big fat liar. I can guarantee you that with no formal education, you will be enjoying a job at Wal-Mart with no health insurance or at a theme park with a lavish $7 per-hour wage. Again, I live here, so I am pretty familiar with wage packages. The reason I went into Real Estate here instead of continuing my 13-year HR career is because of WAGES. There is a huge gap here between the haves and the have-nots.
Maybe you should take some of the wonderful advice given here and get a part-time job now. See how you like working in the real world first before you decide to leave that cushy nest your parents have set up for you.
I am not sure how many more people need to tell you that it is going to be VERY HARD for you to believe it. Again, you are a 15 year-old boy. (I don't care if you act 16

) You are a boy. Get some life experience before you tell the rest of us that are just trying to help you out that we are all wrong.
I wish you luck and hope not to see you operating the cash register at my local Wal-Mart when I am buying my groceries.
