I don't regret the time spent as I'm now something of a domain expert in one of the two and I have some neat hobbies to pursue in my down-time.
With all of this being said, here's the question…
*** How can I find problems other people want/need to have solved without diving all the way in or fundamentally changing myself as a person? ***
I have a healthy social life, but my interests and daily activities don't really align with my peers. Outside of the two aforementioned problem domains, I don't have any itches to scratch, but the strong desire to start an SaaS company remains.
