struggling to find ideas, needs a little help

i’ve watched lots of videos on youtube and other platforms, and i’ve learned how to find low-competition keywords. but when i try to come up with one, my mind goes blank. either that, or i end up with basic ideas that have very high competition or no search volume at all. could anyone give me a list of keywords i should write about? at least having a list or some patterns to refer to would help for future posts. if there are any formulas or strategies, i’d really appreciate it if you could share them. right now, i only have four posts and i’m stuck on generating ideas. i’m okay with any keywords as long as they’re not a review of a physical/virtual product. i can’t really explain my niche, but if you want to check it out, its at my profile :D
