Watership Down was the first book of its size that I read and it had a profound effect on me that has significantly directed my life. I enjoyed it so much that I kept reading after the book was finished. This led to reading and loving anything written by J. K. Rowling, Isaac Asimov, Ernest Cline, John Grisham, Robert Greene, Orson Scott Card (despite later finding out of his personal flaws), and many other amazing authors.
Many years later, I'm still a huge fan of books, although I no longer read as much fiction as I'd like.
Perhaps it's time to sit down again and go on an adventure with some rabbits.
