Sounds like you're thinking about a startup. It's a terrible idea financially and you'll probably fail. But if you have a burning desire that you can't shake, here's my advice.

Are you looking to for a lifestyle business that allows you to work on interesting problems with interesting people or do you want to transform an industry? Don't raise VC money if you're not sure on the latter.

If you're bootstrapping, most startups take a minimum of 12 - 24 months to find sustainable cashflow. You'll want to have 1 - 2 years of expenses saved (at a very modest salary). If you already have cashflow coming in, you can cut this down.
