If someone can work quietly in a corner and churn out a thesis after a few years, does that make them more likely to be able to churn out a startup by themselve

If someone can work quietly in a corner and churn out a thesis after a few years, does that make them more likely to be able to churn out a startup by themselves? I doubt there's a strong correlation here. When you're working on a thesis, you're still within some academic community, have a rough deadline, and have a pretty good sense of what's going to fly or not. Moreover, the progress you make on a thesis is inherently satisfying. You can stand back and look at even a page or a paragraph of work with pride. When you're working on a startup, you spend much of your time working on things that don't work yet or will look and feel like crap for a while. A lot of the problems you solve aren't going to be intellectually interesting, as they would be for a thesis. Which means that there are precious few rewards to be had from the pre-launch development process by itself. I tried to go solo for a while, but found myself crushed by the lack of feedback. Then I paired up with someone (remotely), and if we weren't pair programming, we were at least showing each other what we'd done several times a week and giving feedback. Not only is this immensely helpful in terms of sustaining motivation, but merely having someone else who thinks of things you don't is incredibly valuable.
