I'm glad I did, it was an icredible experience.
I think his books are incredibly insightful, he just hid all the very gripping truths about the world and human nature under the humor. I learned that people do not realize how deep his books are, seeing them as simple fantasy stories with satire.
I also have read his books for over a decade now, ever since I was introduced to the Discworld by my English tutor. I have read most multiple times. I don't know how, but he just gradually settled in my life to a point he became a part of it, part that I treasured and never wanted to give up.
I recently picked up "Night watch" and after reading the first sentence I felt like I had returned home. Isn't it weird that a book, even a single sentence makes you feel so at home?
I watched the Hogfather yesterday and completely lost it at the end, when Death and Susan discuss belief: my favorite quote: "YOU NEED TO BELIEVE IN THINGS THAT AREN'T TRUE. HOW ELSE CAN THEY BECOME?"
