I'm a big fan of reading so this one comes from one of the greatest writers (in my opinion) J. R. R. Tolkin:
“Remember what Bilbo used to say: It's a dangerous business, Frodo, going out your door. You step onto the road, and if you don't keep your feet, there's no knowing where you might be swept off to.”
You've got to like an author who quotes his own book I say. But here I am - I've stepped out of my front door and who knows where I'll be swept off to.
