Will you read all the books you’ve bought?

I buy every book I want to read. I don’t always read the book right away but I usually get to it eventually. Though unfortunately not always.

A friend was visiting and asked if I had read every book I own. When I said no they said they’ve read every book on their shelves. Then asked why I bought them at all? I felt kind of badly about it.

So now I’m wondering if this is a bad habit that’s wasting my money. Should I be more selective?
