Of course its feasible! But is it preferable? No. I want to work on on something for 2-3 years, tops, and then cash out and or move on. I don't want to grind a project for the next 10 years. Life is too short for that.

thats certainly your choice to make, but my point was simply that there is an alternative way to do things. For me, if I could work on my best idea for the rest of my life, and it could go and serve the needs of millions of people (or even just a few thousand) across the globe, that would be pretty cool.

I don't disagree with you at all, but the idea I want to work on isn't going to make me wealthy. I just need enough money in the bank so that basic needs are met, rent is taken care of, and I can go work on fixing homelessness, dysfunctional healthcare systems, etc.
