And we've been on a journey. And the debate has raged, hasn't it, since the Greeks, of isn't it what it's all about? Isn't life about the journey, not really the destination? And here we've been on this journey, and the truth is, it's been thrilling. We haven't reached that other shore, and still our sense of pride and commitment, unwavering commitment. When I turned 60, the dream was still alive from having tried this in my 20s, and dreamed it and imagined it.

-- Diana Nyad

I like this quote only because it contains the words "unwavering commitment", something that Mihály Csíkszentmihályi referred to his book "Flow" as essential to a life full of optimal experience.
