Aside having a solid schedule for your daily hours, which Dhampy mentioned, I think you feel a bit depressed or maybe discontent about where you life is taking you.
You're not taking lead so it's sailing aimlessly.
I think you have the potential and also the talent to be in the university and get through it with a well-deserved degree. The degree that I believe would help you, definitely help you in building your future. Not only financially that you are focused on for now, but also with a better social stance.
The prestige and better chances for finding well-payed jobs you would find these days difficulties worthwhile.
Also, remember that if your drop out you might regret it 10 or 15 years later. Of course it's possible to get back to school but it would be harder on you then.
Try to make the best of your time and also, if your feel that you're lack of desire to carry the weight is something emotional, it wouldn't be a bad idea to discuss it with student advisory or see some counseling. Those people are professionals who are trained to help you to find your through this chapter of life.
