Then you should focus on saving your money first and for most. Gas prices are insane and lord knows that's a big hit to your pocket; then dropping in a turbo wouldn't help. After you have some decent money under your belt you should check out your nearest junior college and get your associates. Believe me it's not hard! Just focus on getting your s*** straight and finishing school. Doesn't matter what it is, but if I was anyone I focus on learning a particular skill you enjoy doing. The semester's will fly by in no time!
When you graduate you'll future will be a whole lot brighter. Then when you find a good job and have money for yourself.... MOD AWAY~!
