The Upside of Stress by Kelly McGonigal, PhD addresses both mindset and stress transformation. She explains that the effect you expect, is the effect you get. If you think stress is bad for you, your body produces chemicals that cause you harm. If you instead realize and believe that stress can be a good thing, your body follows suit. Fascinating and potentially life-changing information on both stress and mindset transformation. For mindset, transformation she mentions several studies that showed you can have a lasting impact on others when you tell them, for example, that they can succeed and make positive changes throughout life. When they believe this and take it to heart, it happens. If you think everyone is out to get you, you will see this everywhere you look. If you think people are nice, people will be nice to you. She cites two studies where mindset transformation occurred and it had lasting positive impacts for people. Highly recommend the book!!
