" It’s a performing arts teacher’s job to teach not to praise. For her, (when she is looking for a new teacher or a coach) the biggest red flag is praise. Tell her what she needs to fix and how to fix it. The rest is useless. Praise is something mommies and daddies give you. Teachers teach."
What @musicamusica outlined above is also true in the ballet world. Any dancer worth their salt knows that the instructor who is criticizing you is helping you and if you are not getting that correction and criticism, it is not a good thing. Instead, it is a sign that they see limited potential in you. Not saying it should be a “Whiplash”-like situation but they aren’t there to stroke your ego. It’s 90% critique and, at most, 10% compliments.
