It feels comfortable to review a lesson. It feels uncomfortable to close the text book and test ourselves.
It feels comfortable to practice one’s jokes in gatherings with friends and family. It feels uncomfortable to do it in front of a crowd of strangers.
It feels comfortable to do train at a lower heart rate. It feels uncomfortable to push past that zone into high intensity training.
And yet, we learn far more rapidly through those uncomfortable experiences than their comfortable alternatives.
That discomfort you feel is your friend. It is the feeling of your body creating muscle fiber, and your mind forging neural connections.
