Clearly distinguish teacher from teaching. The teacher is generally someone with charisma, spirit and good energy who exudes mastery, and their company is at once both comforting and exciting. The teaching on the other hand is difficult, challenging to the point of threatening, and highly demanding – it demands to be taken seriously and it demands to be practised. The poor student loves the teacher but hates the teaching. The good student loves the teaching but is well aware that the teacher is human and therefore fallible. The mediocre student can't decide – wants the best of all worlds.
