It looks like everyone is assuming you are looking for an idea for a startup. You might want to be clear about that?

You can find problems to solve, or find things you or someone else are interested in. On some occasions, there is nothing wrong with looking at other people's ideas for inspiration. Even better if you can iterate their idea and make it better or find a different permutation of that idea.

Get feedback from friends, family, or intended audience.

I usually have hundreds of ideas at a time. If you ever have those moments just pick 10 to prototype out of 100 ideas and 1 to actually build.

PS. always write your ideas down somewhere
