A B2C success is like winning the lottery. I've had some of that and it really feels like that, even to this day I could have never dreamed of engineering something like that. And with a success I mean a substantial income for a decade or longer.<p>B2B is two orders of magnitude easier to turn in to a business, no luck involved there, it's just really hard work and staying power.<p>There is lots of 'advice' floating around and plenty of it is given by people that seem to ignore their own advice, and I think that's the biggest indicator that you shouldn't be following it. Have a look at the people that are building, slow but steady and that eat their own dogfood in terms of advice.<p>Not quitting your school or your job until you make enough money that you can salt away half a year to a years expenses is good practice, and cutting down on your expenses as much as you can is good practice too. It's usually easier to save a buck than to make one.<p>Whatever comes out of that 18 month stint, you are a <i>much</i> wiser person now, so think of it as a school too, only a different kind.<p>best of luck!
