whats your hobby?how does it come into being?

Here's my example:
I love reading most.When I was a little boy, my father bought me a lot of books. Not having other choices to kill the time , I picked up the books and made reading a kind of entertainment. Soon I was absorbed in pictures and stories and became addicted to them. From then on ,I haven't been able to leave the books.
