I love the concept of appropriate effort, which I discovered from the Alexander Technique.
I don’t drive my car any better by tightly grasping the steering wheel. Hit a golf ball further by squeezing my hands around the golf club. Or lift heavier weights in the gym by clenching my teeth.
Anything more than appropriate effort is wasted energy, and will make me tire quicker.
I added the deliberate part, because if I’ve done the work to be clear on what’s most important to me in life, and where I’m headed, there’s real purpose to the activity.
In deliberate and appropriate effort there is calm focus.
