I've been doing the nights & weekends thing for exactly 3 years today (9/11). My project is http://www.obsidianportal.com We're profitable but I still need a dayjob to pay the bills, so take my advice for what it's worth. 1. Shorter release schedule is always preferable. Like others have said 2 years to launch is a really bad idea. However, my question is: Where did you come up with these numbers? Do you have 2 diffe…
My original thought process was that it'd be better to pick a long term ambitious project and launch a minimum viable product for it in two years (not a full project like I think I implied in the original post). As you and others pointed out though, I should shrink that even more until I have something that I can release in months, not years.
I have plenty of ideas, but they're mostly, in pg's words, science projects, not company ideas. See, for example, HNTrends.com. Neat idea, but not exactly something that's going to put food on the table.
There's pros and cons to looking for a big idea. If I identify something that I'm passionate about, execute it well, and lady luck is on my side, I'll be in good shape. But, the longer I drag my feet looking for a big idea, the more I increase the chances that I'll miss out by not simply executing a small idea and gradually growing it into something big. All that said, I think your initial direction matters a lot. I imagine many founders have had great ideas that they wish they could execute but they can't because they've committed to something else which is why I'm taking the time right now to figure things out.
I suppose what it all boils down to doing exactly what you said: find something you're passionate about. that'll take care of almost everything else.
