A good coach knows that human motivation is precious and fragile. A good coach will let you know what needs improvement, but a good coach will also know how to conduct his or her speech so that you never feel powerless, disempowered, or discouraged. On a personal note, I do think that if we worked this skill in ourselves, we would all be much better friends and partners. It doesn't mean that people who don't know how to give feedback don't love us, but we would have better relationships and we wouldn't probably struggle so much with anxiety, stress, and depression in general. Sometimes, the difference between a smile and a tear is someone's words of encouragement.
