It's easy to be overwhelmed by the amount of information available, the varied nature of daily/weekly requirements, and the unclear (although gradually becoming more clarified) requirements for promotion. Success requires determination, a thick skin, and willingness to respond to pushback with the same - advocating for yourself until your job looks like what you want it to look like.
