Ideas for prompts to include in an affirmation letter include things the writer likes about her body and things the writer does well. The most important aspect of an affirmation letter is to keep the tone positive and caring, according to CreativeAffirmations.com.
Another method for writing an affirmation letter involves considering what steps to take in the future to clarify a future path. A more creative type of prompt involves writing messages from the perspective of a 10-year-old or 80-year-old self. Reading the letter out loud while recording it and then listening to it several times per week is one approach to uplifting oneself with an affirmation letter.
