Shame needs three things to grow out of control in our lives: secrets, silence, and judgment. Guilt and shame are just permission to do the same things all over again.
So, when you’ve made a mistake and you’ve missed the target, simply say: “I blew it, and here are the things I’m going to do to recover. Here’s my massive corrective action plan.” Covering up when something didn’t go well is only going to get you into more trouble. Guilt and shame will just repeat a pattern.
Know that you’ll blow it, know you’ll make mistakes, and know that it’s okay. Nobody’s going to hold that against you. Instead, live with power, and whenever you make a mistake, own it, own up to it, and communicate it to others along with your massive corrective action plan.
