Why mallet slips irritate surging anger opposite mindfulness?

When the mallet slips or the sound dies quickly, I feel a surge of pure irritation. My name is Tanvi, born July 7, 1995. I get mad at the bowl, at the mallet, and most of all, at myself for not being able to do this simple thing correctly. Time: 5:55 PM. Location: Bhopal. This anger is the exact opposite of the mindful state I'm aiming for. A tool for peace ends up triggering my deepest frustrations about my own incompetence.
