I own about 600 books currently. Ranging from A-Z in terms of subject matter. When I've moved, it has been a huge hassle to box and move and re-shelve them. My wife gets pretty irritated about this.

I wouldn't change this.

Physical book on specific subject matter tend to be very thorough compared to any content I could find online.

Physical books make me pay attention to it. They are right there in front. No blue light emissions, no notifications.

Physical books cost money. You can never sell them for anything near what you paid. I want every dollars worth our of them.

When someone asks me about a subject, if I own books on them I am happy to part with them and pass them along to that person provided they agree to do the same, if asked one day.

OP, please read more books, on any topic. Your mind, stress, creative spark will thank you.
