I've been really into trying to meditate. For me, idly browsing Reddit or YouTube feels like I'm letting my brain take a break. It's like relaxing not just physically by laying down and not needing to hit buttons, but mentally, I don't really have to think at all. Meditation has been super useful for getting that while also not wasting an extra hour getting lost in a YouTube hole. Sometimes I stand, sometimes I sit, sometimes I try not to think and just focus on my surroundings, sometimes I try to go through my whole day and think about shit.
Either way, I tend to come out the other side feeling more confident about the things I'm doing. It also takes waaaay less time for me than watching YouTube.
