But how about this? According to Steven Toepfer of Kent State University showing gratitude is actually good for you—see Want to be Happier? Be More Grateful. As the man says, to be of benefit to you your letter will:
- “be positively expressive”
- show “some insight and reflection”
- be “nontrivial” and,
- contain a “high level of appreciation or gratitude.”
Meanwhile, your efforts expended toward writing a worthwhile thank-you will help you build upon your own resources of well-being for further career exploration, as Toepfer points out.
