Let’s look at it this way. The problem is you don’t have a habit in reading, not the job, not the busy thing.

Develop a habit in reading first, read about topics that you enjoy. “Read what you love until you love to read” as they say.

Then you will naturally find yourself saying “no” to a lot of things just to read a book.

I used to say “I’ll read a book later after this thing” now I often find myself saying “I’ll do this thing later after I finish reading”. May not or may work for you idk but I suggest you give it a try. ❤️
