Stay in school young man
My opinion is, that if I were you, I would be going back to school as long as possible, or until completion of your associates degree minimum. You are only going to be 18 once and these skills, education, college and schooling in general, are what you are going to be using to earn and pay your way thru life. What you do today will be with you your lifetime, and that may be a while.
I will bet your father would likely agree.
