Leadership with emotion

Our course is now, in a sense, in a bad mood. The reason is from our director. He works very well, but now he’s almost lost his respects from students. It’s really good lesson about leadership for me, because his explanation and responses about our questions and disbelief sounded very logical and appropriate, but the thing is that there are no satisfaction and respects for him. Of course, it might have been just because of stupidity and laziness of students, but anyway the situation taught me that for building proper leadership, logical validity is not enough. There must be some emotional factors.
