You’ll find the answer in the book Jonathan Livingstone Seagull.
Jonathan Livingstone Seagull was a brash young seagull who wanted to learn how to fly the fastest. He experienced both success and failure in life, but ultimately became a master. At the end, when the young seagulls came to him to learn how to fly, he simply told them, “Let us begin with the basics.”
A person who can say, “Let us begin with the basics” is a true yoga teacher.
But a person who tries to fulfil the expectations of the students, forgetting the basics, is not a yoga teacher.
Every system has a discipline. When you start learning maths, you don’t jump to higher maths or algebra straight away; you start with simple addition and subtraction.
That is how a yoga teacher should begin, regardless of what people think.
