Excellent reflection upon the subject matter, well done!

I believe that it is very important for a given leader in a given situation to "barometrically" get an accurate overall reading of the basic personality styles & types of diverse work-patterns and communication devices of their employees (or students, etc.). After successfully doing this, then, find the right balance in their own leadership style to best keep the group motivated, and productively working and doing so out of respect for the given leader involved. This skill requires a real talent for reading people and understanding them.
