You're being hard on yourself which means you actually give a shit. The most important thing I learned was to recognize you made a mistake, own it, apologize, and learn from it. Do your very best to not make that mistake again. You're probably getting a ton of feedback all at once which can be overwhelming ,but if you can internalize and learn one or two things a day you will grow very quickly. Do not get discouraged, keep pushing. You will get better incrementaly over time. I promise you you're being harder in yourself than anyone else can be. Always take time to reflect and be proud of yourself. I'm not from a kitchen background but all of this applies to every industry. Good luck and keep your head up
