This morning I heard Michael Johnson tell BBC’s Julian Marshall (when asked for his reaction to the prospect of having Usain Bolt break all his records) that he is thrilled.

“it’s all about breaking world records, not holding them.”

This is the very best attitude, not just about competitive athletics, but about achievements generally. Or maybe I should say it’s the attitude of the very best people. I am willing to bet that Neil Armstrong, Michael Collins, and Buzz Aldrin are unequivocally thrilled about a possible manned mission to mars and never for a moment worried that it would overshadow their achievements.

As Michael Johnson put it, “you don’t wake up each morning and say, yes! I still hold the world record.”
