It was though, at first I simply switched to surrogate dopamine dispensers which I ended up blocking, only allowing myself access to certain hours for a limited amount of time. Overall: blocking myself from such activities turned out to work well, can't recommend it to everyone though.

I picked up new things by making an habit out of it, such as reading at least a few pages of a book every day. It's cliché, but setting medium to long-term goals also clarified what I wanted my days to be made of, so now I'm very focused on a personal startup project.

Bonus advice that may not apply to you at all: don't be surprised if relatives tries to keep you from changing your habits, or if you find yourself distancing away from friends, it's a feature of improvement not a bug.
