I thought there were magnificent, defined processes that everyone followed. I thought I just had to wait, to stay out of the way of those who knew, and everything would be revealed to me in the fullness of time. But I have learned that there are no magnificent, defined processes to follow. That there is nothing that comes from waiting for revelations. If you do that, you will be disappointed and most likely unsuccessful.
Management is just people working and trying and doing their best.
However, to do your best, you have to know what is expected of you. Do not wait to be told, and fail in the absence of the telling. Do not be bitter that you thought something else, or blame someone else because you were never told. Management is not about being told, it is about discovering. Find out for yourself what you are expected to do and how much time you have to do it.
