It's a gratitude moment. It's standing at the end of the diving board and pausing to remember--not your training, because that's in your muscle memory--but your trainer, your friends, your family, your education, your lover, your past, your present, your good and your bad. All of it--all of it--has brought you there and made you ready. You don't know what's next, but you give thanks.
And then you dive.
And then you laugh at yourself for having chosen a picture of cement to accompany these thoughts.
