Here’s an exercise in patience: try whipping cream by hand using your nondominant hand.
I’d like to say that I have done that, but frankly, I am too impatient. The best I can do is to trade off to my left hand (I’m right-handed) for a dozen strokes or so at a time.
It pains me to be that impatient, but when I am whipping cream, I am dealing with an immediate need. I want to indulge in that cream right away. I are not making whipped cream for some other, later event.
That is the power of immediate gratification. Even a saint might find it hard to whip cream with his nondominate hand.
