(note – not trying to diagnose your symptoms, just responding to your comment about coding being physically tolling!)
Not that I want to presume -- you may very well have some specific conditions outside of the norm... but as a general rule, coding requires you to take additional preventive actions to maintain your health. Because if you let it, coding will trash you.
You however need to value them and not to buy into the "real programmers code whole night and eat only pizza and never exercise" bullshit.
Curious, not trolling. What kind of gastrointestinal issues does one develop from programming / sitting in 1 place? Is it from the cliched "coder diet" - pizza and soda, or is it from the physical aspects - sitting and staring at screen for long hours - and not related to diet, that cause gastrointestinal issues?
Also, bad posture over the years has led to cervical stenosis & herniation. I cannot sit for more than 30mins without developing pain in my shoulder and neck.
In general, I think being if you're an engineer working on services, it is hard to maintain a proper schedule and routine. Add to that strict deadlines, pressure from management, bugs etc and things get worse. It is still a pretty subjective argument though.
Creating a little/niche SAAS takes more than writing code. Most business failures from developers that Ive personally talked to is due to not understating how to market and sell. They thought they could hack it and automate it. This part is still very people centric even if you are not constantly interacting with them.
I dont aim to sound mean but this is akin to thinking that every mechanic out there can be be a successful repair garage owner. Different skills. Its very hard and uncommon to have both technical and business skills. Why do you think YC puts so much money into finding people with both?
Edited for spelling
It certainly doesn't. But it's still tremendously advantageous.
And just as programming can be learned, so too can those business skills. It just requires some combination of reading, mentorship, time, practice, and experience. And that's really the whole point behind the interviews on Indie Hackers, and the community forum as well. To help people learn those skills.
Your comment made me realize that mine came out a bit negative. I certainly agree that business skills may be studied and developed as any others. Maybe Im a little burned out from talking with people who just want a 5 minute solution to a 5 year problem.
I also run a little podcast[0] to help people learn and develop those skills. Its new and very rough around the edges, but the last episode will resonate a lot with software developers who decided to dip their toes on the business end of the pool. :)
Note: Im setting up https these coming days.
