Step One: Get to know what your inner critic is telling you
Notice when your thought process shifts and your inner critic starts to invade your mind. Get a hold of what situations trigger your critical inner voice and what that voice is saying to you in those moments.
Step Two: Think about where these critical attitudes come from
When people write down or say their voices out loud, they sometimes have insight into where these mean thoughts originated. Identifying where your voices may have originally formed can help you to have self-compassion and distinguish these old attitudes from your current reality.
