Constant scrolling social media on your phone gifting you with small doses of dopamine causes this. I used to read a book every two weeks few years ago and I have reached a point recently where books were boring, movies were too long so I watched series only. Realization is the first step. Now you have to make steps to change this. I have swapped bedtime phone scrollig to reading and books again and lowered my daytime phone usage. I have also watch some educational youtibe videos instead of scrolling some social media. It has helped a lot and now I’m back into reading and much more patient.
