The purpose of practicing skills is that you're not getting into a judgy place if you don't get this right. Take a moment to let a corner of your mind observe the processes and some folding and just present these questions to yourself. If it's easier to do it then, ask yourself, did I catch myself? If not, why? What happened? It kept me from catching it was I completely successful in keeping a reaction to myself. And how successfully am I shifting my focus and why or why not? So you're asking yourself these questions that are designed to help you do it better next time.
