Sullivan's child-friendly guide to learning ways to cope with negative thinking offers some useful ideas for counselors. It explains that self-talk can be positive, neutral, or negative.

The book suggests having the student choose 3 positive statements, write them on separate sheets of paper, and decorate. For more ideas, check out the book.
