Thats not quite resume fodder now is it. What do you do well?
Not much. I've been put in a pre-university class six years ago and I had to spend my entire days to even receive lousy grades. I didn't have any time to develop any real talents. My only talent is that I have tons of imagination. That's all.
I was sitting outside the classroom waiting to go in, and I saw an airplane hit the tower. The TV was obviously on. I used to fly myself and I said, "There's one terrible pilot."

Unfortunately, as it is (with your attention span problems, not doing well, no special skills etc.) you'll have problems finding a job even if you quit college. College is a good place for people who have no idea what to do with their lives and want to buy a bit more time and a few more skills to find out what they're meant for.
Being unable to finish anything that you start is also a huge problem. Even if you were to make a living out of channeling your imagination and creativity into some craft, you'd need stamina and perserverence, on top of raw talent, to get anywhere. What are your plans if you quit college? It's definitely not going to look good to employers if you quit after failing a couple of classes.
