The mind's power over you is an illusion. For instance, say one thing while doing the opposite. You will find that it is possible to do the opposite of what you are thinking. (For example, type, I cannot type this sentence, while you are typing the sentence.) Regularly doing this exercise can give you more freedom to do hard things.

We usually feel that we can choose to agree with someone else, while we don't feel we can choose to disagree with ourselves.

By giving your mind a name, you can feel separated from it because it is now different from you.

Consider having a conversation with your mind wherein you appreciate what it is trying to do, but knowing that you don't have to agree.

This method is useful when you have a thought that is nagging you.  Sing something like "Happy Birthday". The thought does not have to go away. However, you will see it more clearly as just another thought.

Write down a recurring thought. Maybe its "I'm stupid" or "I'm unloveable." Then look at it as if it is something that is no longer part of you. 

If you are willing to honor that history, carry the paper with you and acknowledge it as part of your journey.
