1. Idea is not "lets do X thing but the twist of Y" - it's just an emotion, sentiment, vibe at best.
Ideas is "this is how people do X, they spend/make Y amount of money of it. If they use my product that does Z instead - they will make/waste Q amount of money/time. Where Q is _significantly_ less/more than Y. I am confident this estimation is correct because: a) i know/have first hand some actual real world example of it b) i use some _very_ similar examples that support this"
Only then you go check and see if there is a real demand and you have a necessary skill to deliver.
2. Aggressively use money filter for your ideas - it is not ideal but only good enough measurable tool we have to estimate something's worth. Including ideas and your time investment in pursuing them.
For example if you apply this filter to many so called "micro" saas things you may end up concluding that it is far more profitable and reliable investment of your time to score a good FAANG position. Of course there are many other considerations, but money is the best starting point.
If money doesn't concern you at all — you're in the artistic domain, not in business one.
Then just go and create whatever and however you feel like.
If you're talented and lucky enough - something will stick some day.
It's useful to stay within some niche for enough time to build solid skills. To have a backup plan of regular job if you're not lucky.
