I hear a lot of people be incredibly critical of TikTok, while being active consumers of Facebook/Instagram/X/etc. I've found the content on TikTok to be much better curated to what I actually like, with just enough (i.e., very little!) other content sprinkled in occasionally.

I asked someone a similar question to you a year ago and they told me something like "just spend 15 minutes with it. Aggressively swipe past things you aren't enjoying, like the the things you like. Search for something you are interested in too and like anything you like there". My feed is currently entirely basketball coaching tips for kids, cooking & recipes, stand up comedy, basic DIY, fitness/running tips, local restaurant recommendations, and sports highlights.
