BMI, diet, yoga, workout … all demand mental effort, focus and stress.

A bullet fired towards a target is in free motion… hit or miss, but for a missile to aim at a moving target and adjust its flight, control is required.

As soon as we set an (however vague) expectation and take aim, we take on a challenge and set ourselves up for stress, disappointment, pain, self-doubt … Our self-esteem is now at stake.

Similarly the coding drill…

My son may not have this self-control yet.
