Ask HN: Leaving college to work on a startup?

I am a college student, and recently I've been rather disenchanted by academia. For years I have collected and combined various ideas, and I am to the point with one where I feel confident that I could start a successful startup around the idea. The problem is that I do not yet have a college degree. What benefits would I have with staying behind and putting the idea on the backburner until I get my degree? While it might be more difficult to do so without a degree, should I attempt to find venture capital and see where that takes me if it becomes available? I really have no other reason to finish the degree, and I feel like my time in college has, for the most part, been a waste of time. However, if in the long term I end up needing the degree, I can always come back and finish. Thus, I see no reason to wait to work on my idea---can anyone else?
