Some people I know wonder why I post so much on G+, Facebook, Twitter, etc. What if strangers find out I'm not home? they ask, and their hints of fear rise -- clients firing them, job interviews lost, relationships broken, or just acting dumb. But my motivation is just this: I'm exposing myself to randomness. All the best things in my life have occurred because I stepped outside with no plan and no idea what I would do. A former newspaper editor was a dick; he called the office one day, asking for a ride, I gave it to him, we ended up friends and when he left for a hot-shot consulting firm, he called again with a job offer that changed my career to marketing. Or in the most important moment of my life, I stepped onto a college sidewalk -- a one-way path across a campus green 200 yards long -- right next to a gorgeous redhead in spandex and a crew shell. I wouldn't usually approach such a girl, but we had to talk, for about 10 minutes. 15 seconds earlier or later I would have missed that chat. That girl is now my wife. Randomness is cool. Start typing. Get the fuck out there.
