One thing that my French teacher once told me is that there are two types of students: those who need praise more and those who need criticism more. Some people work better in comfortable environments with lots of encouragement, while others work better under a bit of pressure, without sweet-sugaring criticism. That’s not to say that the first type doesn’t need any constructive criticism or that the second type doesn’t need any encouragement. And also the first type isn’t any better or worse than the second one, but if you know yours, it can help you a lot when learning! If you’re the first type, then working under somebody who’s always harshly honest, even solely for good reasons, because that’s their type of teaching and their character, you will not be happy under them. And that’s okay! It just means you’re the first type and you need teachers who will encourage you, teach in a way that fits you best! But also type second teachers aren’t bitches, they are just people who prefer being honest and are okay with plainly pointing out the mistakes to people who are okay with that type of teaching/learning. In my experience, they have always been amazing beautiful people who cared for their students deeply.
