Talk with friends to solidify it
After you privately internalize a belief, talk about it with friends. Explaining it to different people helps you refine it. They might see an angle or consequence you hadn’t considered.
You hear it for the first time outside your own mind. You’ll hear it sound wrong or right when telling someone else.
It feels like an announcement. It helps solidify the decision. You can ask them for help to support your choice, and to hold you to it.
We know ourselves through others. If people say you have nice eyes, then you must have nice eyes. When your friends acknowledge your belief and echo it back to you, it really feels like reality.
This piece all makes sense.
In my calendar notebook, I used to write down the nice things people said about me. Good for my self esteem, and reality, and a good source for affirmations.
Too bad —or else so good— that my self esteem became so fine that I stopped writing such things. Sometimes I will thank a person, saying Mark Twain's line: "I can go all day on a good compliment." But then I forget to write it, and it's gone like a joke.
