This is also my usual understanding to TikTok although I know some people found new hobbies with it like the other replies, but the contents don’t click me because they are way too flashy and stimulating, and these really make me visually and mind fatigue.

Your situation is similar to why I have quit Pinterest. Memes and jokes are fun, and some of the images are inspiring, but it simply wastes too much valuable time which I can learn something new or take a deep rest.
