Classes

So I'm about halfway through my CS degree and been thinking about this a lot lately. I have a side thing going that actually makes me money, nothing crazy but it's real income. Classes are fine I guess but it's hard to stay motivated when I'm sitting through a lecture on something I already figured out the hard way six months ago. Not trying to drop out or anything, more just wondering if anyone else felt this way midway through and what ended up making them stick with it (or not). Did the degree actually open doors for you or was it more of a formality at that point?
