I have a lot of catching up to do

I'm currently reading Malcom Gladwell's book The Outliers. Having read Blink, I'm already turned on by Gladwell's mixing of sociological studies, pop economics, and great story telling. I love how he intertwines the stories of real people with statistics and abstract ideas.
I have to say though, now that I know that it takes about 10,000 hours of something no matter how much talent you have before you can master it, I feel a little behind. Behind in what? I don't know. I've always been good at several things. I suck at most things mind you, but my abilities in certain things, like drawing and writing and my enjoyment of them have been noticeable since I was a little kid. But my mind and my interests wander soooooo much. I've wanted to be like a billion different things "when I grow up".
Now I've finished art school and I've decided that although I enjoy drawing and making things, and I think human creativity should be something that is fostered in every person's life, I dislike the art "world"; as an institution and industry, and I have no desire (or aptitude) to do the professional tasks that go along with being a serious artist.

This September I'm going to be starting (over again) studying sociology at the University of Florence (in Italian). I am only 22 years old, but I can't help feeling that I've squandered a lot of time by being unfocused and undisciplined. I really like being interested in a million things at once and it has made my horizons wider than most of my peers, but I also sacrificed stability and practicality and depth. I still don't really know what I want to do or how to get there. I look out at the world and see a billion possibilities; a world so full that I couldn't even get a glimpse of half of it in one life time. I want to know and see everything, which is awesome, but also creates difficulties in structuring my life.
In some ways, my natural abilities have actually made me incredibly lazy. In school I never studied or did homework because I could pass tests without a problem as long as I had taken notes during class (I could remember them visually on the page). Homework was always done at the last minute or not at all, unless it was something I was really interested in. In high school it was relatively easy to breeze by like this, especially since my teachers liked me. In university it's been much harder. my growing lack of interest in art and my frequent "dark" periods made things worse. If you look at my transcript you can see that over the years I have failed or got dismal marks in some of the most basic courses (colour thoery...) and got 90's in the most difficult ones (psychology, post modern philosophy).
Oh god, must stop ranting. WHAT AM I DOING WITH MY LIFE?
Thank you Malcom Gladwell, for kicking me in the ass and reminding me that I wont go anywhere without a loooooooooot of hard work.
p.s. super entertaining book.
