Learn How to Receive Criticism
Because they take criticism personally, perfectionists frequently struggle with poor self-esteem. However, it's critical to receive criticism that is constructive. It's OK to point out to others (and to yourself) that mistakes are a great way to learn.
An attitude adjustment might be helpful if you frequently see criticism as an attack and respond defensively. Your less-than-perfect performances can be turned into valuable stepping stones on the path to excellence through constructive criticism, which can give you valuable insights on how to improve your performance. Try to understand that constructive criticism is expected and beneficial because it can help you improve!
