I have received this question a shipload of times: “but why?”
Why give up your job, your security and benefits? Why make something you don’t even know someone else is waiting for? Why spend so much time and money while you could invest it in something else? Why make your wife’s and children’s life so difficult (that’s the most difficult question)?
That’s a difficult question, and there’s no easy answer, this is as close as an answer I can come up with: http://wethenerdy.com/inside-pete-a-kickstarter-project-by-sector-32/
