Out of the Blue

What I mean is, I didn't start running because somebody asked me to become a runner. Just like I didn't become a novelist because someone asked me to. One day, out of the blue, I wanted to write a novel. And one day, out of the blue, I started to run--simply because I wanted to. I've always done whatever I felt like doing in life. People may try to stop me, and convince me I'm wrong, but I won't change.
-Haruki Murakami, What I Talk About When I Talk About Running
