by Tom Swift

Unless we fully give ourselves over to our endeavors, we are hallow, superficial people and we never develop our natural gifts. We’ve all known people who, like monkeys, mimic whatever seems novel and flashy at the moment. But then their enthusiasm and efforts wane; they drop their projects as soon as they become too familiar or demanding. A half-hearted spirit has no power. Tentative efforts lead to tentative outcomes.

-Epictetus, Manual for Living (1994, Sharon Lebell translation)
