The thing about feedback it that the only real feedback we can give to another person is 'how we experience them'. That's the only 'truth' I can offer another person - my experience of them in a given situation and of course, they of me. Thats because everybody's truths are slightly different - an experience/event goes through our own set of values, beliefs, past experiences and filters and comes out as a 'perception'. That's a perception we own and therefore we call it our 'truth'. But to call it the truth is perhaps not quite accurate.
I say this because we as coaches are in the feedback-ing (is there such a word!) business daily and it's easy to come across as being judgmental. Using phrases such as 'my experience of you in this situation was....' may be helpful. After all, we only offer feedback (and we should be offering it rather than just giving it) because we believe the client/athlete/player will use the information to become better and that we have faith in their potential.
