It's a really great habit. Here's my personal take: https://blog.gpkb.org/posts/make-reading-habit/

But like many things, you do have to do it for the right reason. If you go into it thinking it's going to "fix" you, then you won't enjoy it, you'll just be wondering how many more pages are required before you're better. I once read Hyperion because a crush has read it. I didn't enjoy a single page because all I was thinking about was her. Almost missed out on one of the greatest pieces of fiction I've ever read, as discovered with a recent re-read.

Whether it's the gym, reading, learning, socialising etc, you've got to make it about you. You need to understand that you are the one and only constant companion you have in life, whether you like it or not. Once you become comfortable with yourself and being happy alone, other companions will join, if you want them to.
