"But usually after two to four weeks, the project just fails. We've lost faith in it."
Well there's your problem. Assuming you are working part time, two to four weeks is not even remotely enough time to build even the simplest of businesses. Note I'm not talking about building an application, which you could complete in 3-4 weeks, I'm talking about building a business.
I would guess a more reasonable timeline for starting something in your spare time would be about 6 months until you get your first revenue, (or more likely your first 'pivot' because you finally have enough data to realize your idea sucks). I wouldn't be surprised if it took longer. So, whatever you choose to do, try to ask yourself if you are willing to spend most of your spare time for the next year working on it before you even see any money. As soon as you start passing ideas through this filter, I think you'll find more success.
Any more optimistic timeline is a time fantasy.
Side note: this is in my opinion the problem with starting something on the side. It's far too slow. Sometimes it looks like I'm going to be 30 before I make a dime! I think I could cut down this cycle to 2-3 months to my first 'pivot' if I was full time. In other words I think working full time would move things along 4X as fast. Add a competent cofounder and you could probably almost double that.
