You were a non-reader, preferring to watch movies and series rather than touch a book.
But then, someone recommends a novel they think you’ll like, you flip through it and love it!
In case it’s the first part of a trilogy or series, and you decide to read the whole series (or at least read all the parts you get your hands on and, in case you can’t get your hands on the last ones, you decide to look for spoilers on the internet).
That was my experience with Warriors by Erin Hunter.
What’s yours?
As a kid I went through every Tom Swift book. Then Mike Mars, Astronaut; Tom Corbett, Space Cadet; Everything Tarzan and related. But Swift was the first. I got a dollar a week for allowance, went to E.J. Korvettes, which had a book section, and bought the latest release. This was about 1960 or so.
