I can relate to your situation. I quit my very well paid i-banking job last week as I had no passion whatsoever and started really hating what I was doing. I was full of plans but a few months into it I realised that what I was aiming for was too big a job. It took me another few months of starting out different, almost random things (without ever getting anywhere) before I recently, nearly by chance, stumbled across an idea that was small enough to build a prototype for in a couple of weeks and seems to have hit some real demand out there. It's a github like thing for spreadsheets that allows people to do diffs and stuff on their spreadsheets. And here's the irony of the story. My old job that I hated so much involved a lot of Excel monkey work. When I quite my job, it never even occured to me that this could be a useful thing as I was chasing some high-flying fancy idea. And the fact that I didn't have financial pressure didn't help much either as there was never really the need to get something off the ground quickly. So the short of it is, (though I don't feel like I'm really in a position to give you any advice), maybe you can find something that makes use of what you did before? Even though it might look like a tiny little problem not worth pursuing? There's so much talk about building something disruptive these days that the little problems people deal with get overlooked so easily. And quite often it doesn't have to be a cutting edge complex engineering solution. So, please, don't give up and don't look back. If you hated what you were doing, it's not worth it.
