There is an idea.
You write it on a piece of paper, but there is an accident in the way.
Instead of putting it away into the drawer with the other ideas, you hesitate without warning.
The idea stretches and breathes.
And then: the idea is no longer the snowball at the summit, it is now the avalanche heading for the screaming villagers at the foot of the mountain.
It is in these happy accidents that the future is made. And, from time to time, we thankfully let them happen.
