When I was in high school in the mid-90s, I emailed Douglas Adams, who freely gave out his email address at the time. I told him how reading "The Hitchhiker's Guide to the Galaxy" got me more interested in my Physics class, and generally helped introduce me to a world beyond computer games.
He wrote back:
"Thanks for your note. Glad you enjoyed the books. I'm glad if I got you interested. But I'm always surprised that people are surprised to find that the world we unexpectedly find ourselves in is interesting.
Best,
Douglas Adams"
Not his most pithy writing to be sure, but I love that I have this personalized bit of Douglas Adams wisdom that nobody else has ever seen (well, now they have).
