All great tasks test our motivation. It's easy to court ideas over beers and change the world with napkin sketches, but like most things taken home from bars, new challenges arise the next day.

To do interesting things requires work and it's no surprise we abandon demanding passions for simpler, easier, more predictable things.

When I'm the speaker, I know that special moment [just before speaking] is the only time I will have the entire audience's full attention.
