I am running a startup after years of waiting for the 'best idea'. I realised, if I had started somewhere instead of waiting for 'the one idea', I would still have learned a lot and that would have been financially better too (by getting better jobs with that experience etc) So, now I started this startup, which I know makes money, and I know I can run it. Problem is that, this business is not scalable. The reason I did this because I thought, 'this will not retire me, but it will take me from A to B, ie make a million or two' (hopefully). I am very confused over past few months, that we haven't made any progress in our startup due to not having any direction. I have another idea, that is scalable, but Uber like margins, not SAAS margins. I think answer to my problem would be straightforward to you, but I am too blinded.

How would you make a decision in this case?
