Motorcycles have been a passion for as long as I can remember. Cars too, but a car carries you; a motorcycle asks you to take part.
Riding is the most present I ever am. A mountain road leaves no room for a stray thought: the line into a curve, the moment to brake, where to look, how far to lean. It is a lot like a hard problem at work, only louder and with a better view.
It also taught me a few things I bring back to the keyboard: prepare before you start, respect what you do not control, and never confuse confidence with skill.
