Need help managing my time and also procrastination

[lalalallalal]

yo, i've always been a curios kid and always want to learn many kind of skills. but this past few month i've been struggling with something i've never experience before, mindless scrolling to tiktok and youtube for half of the day. I have fun time entertaining myself but idk if im wasting that time and also scared that if I focus on learning/trying different stuff, i might miss out something and left out.
.
there are alot of encouragement saying that a person "fun/enjoyment" time are not wasted, but idk if im wasting it or delusional.
.
please help
