Blaming is useless. It is a smokescreen, a blind, a weight that drags you down and doesn’t get you anywhere. It is important to notice this as soon as you are frustrated and start blaming. Catch yourself. (This takes practice—you have to be quick.) Then focus instead on observing the actual feeling of frustration.
What does frustration feel like? Does your breathing tighten? Do your shoulders tense up, or does your face get red and hot? Do you clench your teeth? Your fists? What thoughts fly into your mind? Are there memories that come up? Visual images? What is frustration really like?
Oddly, if you accept frustration as frustration and study it without trying to relieve it by blaming or becoming angry, it will not overcome you. Instead, it will dissipate fairly quickly, or at least more quickly. You will simply digest it naturally.
Every human being already has a degree of persistence: we need some persistence just to stay alive, to hold down a job, to keep a human relationship functioning. All of us show up for our lives to some extent. We are all more patient and forbearing than we know, and we should recognize this and congratulate ourselves for it. We don’t need to create the quality of persistence out of nothing. Rather, we need to expand and strengthen the persistence that is already there. Cultivating persistence takes persistence.
