how to find a niche

Hi All, I've been on youtube for a while now mostly just doing fashion or lifestyle based videos but I don't like sticking to one specific niche as the videos are limited and I like doing whatever I find interesting and that I genuinely would watch, but do I need a niche to grow my channel? And...

I have been thinking for about a month now and I still can't find a passion or niche that I love so that I may be able to do it on youtube. If your have and tips then please reply I would really appreciate that.
