Am I being completely unreal?

Do both. Talk to these guys, make a time commitment, and you can pull both of these handily. Just don't count on too much sleep.

Some things to consider - there is a certain glamour to the startup life, and certainly you can make it big. Statistically however, you will lose money - so if you are chasing gold, chances are it's a pipe dream. Certainly there's a chance, but you are gambling if you are just going after money. If you are going to do a startup, do it for the experience, and for the act of creation, but not to get rich.

Not having a degree, you are going to get yourself into a tough situation though. If you ever decide to get a job at an established company, you'll face a couple of things: first, HR will probably throw out your resume, and even when you get interviews, chances are your knowledge won't align with what they are testing for (algorithms, mostly). Plus you might run into the issue of investors not taking you seriously.

Certainly school will always be there - you won't ruin your life by not going back right away. Yet I think these are all important things to consider.

* Everybody else on your team is an engineer or developer. Obviously, this doesn't mean you can't be successful (I know, I know - look at Google), but you should consider the possibility that you're probably missing vital skills needed to compliment your startup's technical prowess. From UX to business development, you have to get a lot right to turn a great product into a great business, and that can be difficult when you have three other chefs in the kitchen who all cook the same cuisine.

* Starting a business with three close friends seems nice on paper, but don't assume that good friends necessarily make for good business partners.

* Talk about arbitrary dollar amounts calls into question not just your sense of reality, but your motivations. Can your startup raise $1 million? Perhaps. Will you have $10 million in cold hard cash in two years? Perhaps. But you could buy a lottery ticket and win the same amount within the next two years too. If you wouldn't plan your life around a potential financial windfall from a lottery ticket, why would you plan your life around a potential financial windfall from a startup? The number of self-made 24 year-olds with $10 million-plus net worths is quite small, but you probably already know that.

Look at your results so far. It seems from your writing that your intrinsically motivated to learn and execute.

Really good teams coming together is a rare phenomenon. Go follow your passion.

Just keep aside enough money so that if all goes to hell you can start your degree afterwards.

what about the studies themselves? From what I read here, most don't seem to have too much appreciation towards them.
