Study the list. For each item she said you need improvement. Write a short paragraph on what you will do to improve. Then start working that list. Give her two weeks to notice the improvements, then ask for another lunch meeting to review the list with you and get her feedback on your ideas for improvement. Document that meeting in an objective way. Implement any additional improvements she offers, and repeat. If nothing else, you'll throw her off-balance. Demonstrating that you are listening and trying to improve is the best way to turn around a bad relationship and put her on notice that you intend to excel.
