I think that they are incredibly difficult to find and most people (me included) can't identify "problems" in their day to day that could be improved by something - in hindsight - relatively simple.
I'm constantly asking myself: where are the pain-points in my daily interactions with computers/software etc.
So far there's nothing and I know that can't be true.
A big part of this is when you work on computers / with software all day, you're looking for pain points in the same place that most other developers are looking. There is certainly room for improvements in this market but it's generally much more saturated than others. (Hence the common advice to go work or talk with people out of the industry for awhile.)
Otherwise the best advice I'd give for finding problems is to start making a log of every time you get annoyed or frustrated at something. Your package didn't get delivered on time, you realize you have no milk when you're in the middle of cooking a meal, a driver on the highway is endangering people, your phone is too big for your pocket, radio stations all seem to play commercials at the exact same time, your home ran out of heating oil and no one will deliver until Monday, your hard drive failed and you realized your backup program wasn't including a new folder of vacation photos, even though you make an appointment at the barber/doctor every time you show up on time you show up you still wait 15-20 minutes, there's no Mexican restaurants that deliver to your house, you never know how your child is doing in school until they get their report card at the end of the semester.
There are dozens of tiny annoyances that we run into every day. Some have easy solutions, some less so, but they're there if you know what to look for.
That's because thinking of it in terms of pain point isn't necessarily helpful, since people have different "pain tolerance" when it comes to technology.
Try to think of it in terms of outcomes.
What are you trying to do with computers/software, and how could the outcome be massively improved/democratized?
Im a bit jealous of people building a billion dollar business that solves a problem that could literally be solved in ten minutes. The business are rarely about a better solution, its more about a better business model and better marketing!
Better marketing sometimes is the better business model.
Can you do basic scripting? Can you do advanced scripting, with such revolutionary capabilities as calling out to external APIs for stuff like OCR?
Then rejoice! As you have the potential to make your very own billion dollar business[1]! Just leverage those skills for process automation, market it as "software robots", leverage the existing perception of "robot replaces human" to make the recurring $10k/year cost for your automation script seem like a steal compared to the labor costs of a human, and through in some AI references for a bonus multiplier on your valuation potential.
Process improvement and automation has been a thing for ages. Marketing it as "software robots" is much newer. Turns out that particular phrase resonates really well with the target market.
