Lucy has been taking swimming lessons, and today she swam the short length of the pool BY HERSELF. Maybe. Jason wonders that the swim instructor may have had a single finger under Lucy...which means it doesn't count? I'd argue she did swim by herself. How much can a finger be doing except giving her the confidence to do what she knows how to do?
All of our accomplishments require the buoy of confidence. Sometimes, my entire job is holding a finger under a bunch of bright creative people who don't quite realize they know how to...swim.
Watching the Olympics echoes this sentiment for me. Sure, there's the years of training and sacrifice, but confidence: that's the extra something.
