You seem particularly anxious to do the things that you want to be doing right now, because it's a waste otherwise, because time can be wasted. I would tend to chalk that up to anxiety about the future, the world you live in, and general hopelessness about your place there. Why do something if it takes your limited time away from the other thing? Maybe some existential dread coming into play, a healthy dose of "oh god I'm going to die a financial consultant with no friends blah!"
I have no answer. I can only say I've been there, I've given up on school because of the same reasons, and I regret it. I would write music instead of work on papers, dropped out because I didn't think any of it mattered if I couldn't - look at what it takes to make it in the "democratized" indie music Revolution(R) to have some idea about how I'm doing. The hilarious thing is that my university had an exceptional music department; I could have just transferred, and learned some more standard, accepted practice for my composition, gotten some work teaching guitar, etc. Instead of being a janitor for six years.
So yeah. The realization that you will not do better by backtracking and abandoning the opportunity directly in front of you is hopefully something that can be conveyed through writing. I think the best solution to getting through it with any kind of financial security is sheer pragmatism and honesty about your skills and how you can sell them. If you don't know how you can sell them, find out. If you don't have the skills that go with selling them, get them. Spend a bit of boring now, have security and satisfaction with your work later. It seems obvious in retrospect. There are probably people making money in some way similar to how you'd like to. They probably aren't that special or exceptional compared to you, they've just done the work and research involved with finding a niche and squeezing money out of it. And it might be hard work. But it's still probably not luck.
Don't quit school. Instead use it as a place you can find those things out. Take the career consulting resources you have available seriously, take the critique and criticism you can gain from your professors as a clue to what you may need to work on in relation to what you want to do, rather than a judgement on what you should be, and you can make an informed decision, rather than throwing your hands up and giving up - trust me, from personal experience, the bitter satisfaction you get from saying "the world sucks, and here I am" is short lived and needlessly self-destructive. If I'm out of line here, or depressing, I apologize, but that's what it sounds like to me.
edit: I guess TLDR, look at what you're doing to procrastinate. If it isn't what you're at school for, go to school "for" that instead (really more like around it - learn stuff that relates to it at least). Keep moving, keep a goal in mind, be realistic about what your life is going to be like at the end of it all, but don't obsess over how much time you're taking to get there, because unless it's really something you can make a living on without university, it's going to cost you more in the long run to rough it.
