Resolving to run 1 extra mile more than what you comfortably did during your last run is the stretch.
The piece of content that you produce on the day where you didn’t feel like writing at all is the stretch.
The new and at times intimidating responsibilities that you take on at work is the stretch.
Growth doesn’t happen when you’re doing what is familiar and comfortable, it happens when you reach a point where you feel at capacity, uncomfortable perhaps, and out of ideas but resolve to keep on going just a little bit more.
The stretch is the art of playing right at the edges of your limits, knowing that if you push too hard, you will burn out. And if you push too little, you will never realize your potential.
