I had a friend who started his CS degree at the same time I started learning on my own, and he is just about to graduate while I've been in the field for about 2 years now. So it worked out for me to not seek a degree.

He's also a vastly different person than I am, writing code is not a passion of his, while it is of mine. I'd be writing code whether or not it was my job, while he'd rather be doing other things.
