When you're out running, it's not until you pass the first hurdle you start to enjoy it.
Then as the strides get more comfortable, the mind gets quiet. Each leg going in front of the other. You don't have to keep thinking about running.
When the sports star gets interviewed after a big game, the reporter asks, 'How did you do it?'
'I don't know, I just let it happen.'
When they threw the best pass of the game, it's unlikely they were thinking about that thing Peter did to them 10-years ago. They probably weren't even thinking about the pass. Their mind was quiet.
Great thoughts come to a clear mind. But a clear mind doesn't mean an unprepared mind.
Do the preparation you need. And when it comes to show time, get quiet. Let it happen.
