Monitor the inner voice
The inner critic is on repeat for the majority of individuals. If you pay close attention, you'll probably see a succession of your "top ten hits" that you're rating yourself on. Look for words and phrases like "I should...", "I'm not... enough", "I'm too...", "I always...", or "I never..." to help you recognize these thoughts. Once you've identified these recurring songs, take a few minutes to select one and do Byron Katie's reflection activity. You will respond to four questions: “is it true? can you absolutely know that it’s true? how do you react, what happens, when you believe that thought? who would you be without that thought?”.
You'll soon realize that your judging ideas aren't entirely accurate. Most people feel that their thoughts are true, but there is enormous power in being able to hold them up to the light, evaluate them, and determine whether you want to let them drive your actions.
