To me, reading a book is a huge achievement
I like reading, but books are really fucking long. It's hard to find the time for them. It's a big commitment to set aside some time everyday for the next couple weeks to finish the book, something's bound to come up to disrupt those plans.
Plus they take a lot of dedication to finish. It's easy to start a new book, it's new and exciting and you have a lot of interest and motivation to read it. Not so much when you're halfway through it and it's not as interesting as you imagined, but you still want to get through it to educate yourself. I always end up "taking a break" from the book for a few days, promising myself that I'll get back into it soon, only to just abandon it altogether. I just finished a book that I started about three years ago but kept abandoning, and I'm really proud that I've finally finished it now.
So it's always a huge achievement for me when I actually finish a book. And it's annoying then when people recommend a book to me as casually as if it's just an afternoon's work.
