In the summer of 2012, the "Charity Ride" my son and I created, "500 Kindnesses" that would take us over 1,500 kilometres by tandem bicycle from Toronto to NYC came *this* close to failure. It wasn't a freak thunderstorm, accident, or even a huge mechanical failure that stopped us. In the end, the biggest risk to my project's success was my own imagination.
Looking back a year later I'm really glad it happened the way it did. Whenever I feel any self-doubt I think about this story.
