We've been modestly successful. I'm not super wealthy but can bootstrap something small. Money no longer motivates me, what problems should I work on that are tractable but also impactful to society?<p>I've worn many hats: primarily software development, trading strategy development (obviously), and finding signal within large, noisy datasets.
It's pretty general. My fear is working on something "cool" but that won't have much more of an impact than me just amassing cash (which can be done more efficiently the way I'm doing now than anything else I can think of)
What does motivate you? The answer to that will inevitably lead to the answer to what you should work on next.
