I assume you probably tried 'scratching your itch' and it isn't really going anywhere from there.

Not all itches are opportunities. All great, subtle opportunities lying out there may not necessarily happen to be your itches.

That said, if you are looking for problems i.e your problems that you want to solve, but just couldn't find something, then what's wrong is that you aren't doing a lot of things.

Go shopping. Watch out for things that you think could be made better. Accompany a friend to a hospital. See what solvable problems lie in the process of treating a patient in a hospital. Experience a lot of things. I'm sure you'll eventually hit on something that you can solve.

Another good exercise is to look for things that qualify as unsolved problems in different domains/industries. This isn't tough. HN's Who is hiring thread is a great place to start. These threads are a key knowledge base of people working on problems. Go ahead, just do a HN search and you'll realize there's a lot of things waiting to be made better!

"What are good ways to find startup problems to solve?" - is a deep question. If you do crack things out (and I'm sure you will), please make sure you share it with the community :)
