Visit a highly populated city sometime and visit the slums. See how welfare/low-income people and the homeless live. If you stay on the path you're on, eventually you'll wind up being one of them. That should be more than enough motivation for you to fix yourself up. You're still young so you ~can~ change things and improve your life, but you should do it now before things get any worse.
