I highlight often when reading on my kindle. I have created a small program that scrapes my highlights and sends me a daily email with one of them. I get it before I wake up and it’s the first thing I read once I check my email (usually that happens after my morning reading).

I find that this helps remember books that I read years ago, and usually the single quote is enough to jolt a series of memories about the book.

That said, I also own physical books and they are in glass bookshelves around my office and living room. I do like the looks of them and they can be a conversation starter as well when friends come over.
