When I was a kid, I didn't care for reading very much - but I was into animals. Then one day with my parents at the local drugstore, I spotted a book with a kid turning into a jaguar on the cover [0] and begged my parents to get it. I was a bit lost, since it was in the middle of a series, but it was the first book I remember wanting to read, and it was also my introduction to science-fiction. From then on I always had a sci-fi or fantasy book nearby, and I still have my original copies of that entire series.

Because of that, and from what gradeschool friends have said, I've always been of the opinion that reading is too often introduced to kids the wrong way, through textbooks or very dry non-fiction, instead of through topics they'd actually find interesting.
