Pick a goal and stay focused. Wake up every day for the furthering of that goal; make decisions for the long-term to attain said goal. Even down to things as simple as who you hang out with. For now, see the people around you as potential to move up/on in life. If they can't help you in that regard, discard. There are 7 billion people, don't waste your time on the ones that don't matter.

I think, if you have the willpower and determination, this will work out.
