My wife gives me a hard time about keeping books I’ve already read or are unlikely to read. Maybe she doesn’t give me that hard a time, but she always questions why I keep these books around. Though I didn’t realize it until now, I keep books around for the same reason Seth Godin does:
I used to have 3,000 books in my old office. When I moved to my new office, I gave away 2,500 of them and I miss them every day—not because I opened them, but because looking at them reminded me of what was inside.
And that seems like reason enough for me, too.
