Well, sometimes the meaningful moments arent quite so meaningful, and THAT doesnt help... Like, exercise is nice and all, but it's made a million times harder if it takes a form you dont like or is boring.
Have you tried looking for different methods of exercising? Like, I know if I were using a gym, I wouldnt last more than a couple of weeks... because it'd be super boring (it never exactly changes much) and there'd be a bunch of people there.
But, going hiking through forests and such? I aint gonna tire of that.
It's the same with other things.
Why not try looking for a constructive hobby? I mean, a hobby that involves the making of something. Could be art, could be, I dunno, origami pigs, whatever. Something that takes time and skill but results in something that you can hold and show to others, and gain more skill at as you go.
It's something I have to deal with as well, for what it's worth. That tendency to sort of get "stuck" to the internet. And indeed, getting additional hobbies was what I needed to get out of it.
Overall, give your mind more to do, and you may find yourself doing the "nothing" of watching the internet less and less.
