I'm thinking about my own software house and I'm very serious about it. Right now, I'm in my first year of studies (got Bsc, pursuing master) and I have a feeling that I would have to drop out of the university. Since, I don't have much experience the risk of fail is pretty high (f.e. in terms of financial liquidity - eastern Europe, not many angels/VCs).
My master's really sucks: nonlinear dynamics, quantum CS - don't enjoy it. I love programming and I love building things. I made a few mobile apps from scratch and I happy that people buy them.
I think I'm in a similar situation as Joel Spolsky (he wrote one blog post about it). I do not want to jeopardize my carrier and burn all bridges, but I don't see any value in it.
What do you think about a kiddo that dropped out to do a start-up? Is it better to stay and finish college?
