I had a client lamenting that she did not know all the details of a project she was working on. She understood the bigger picture and knew what she needed to do to accomplish the task, but she fretted because she had yet to learn some of the finer points of the work.
Yet. She had yet to learn them.
Whenever you are working on something complex, no one knows all the details. If you are competent in executing the overall structure and goals, the rest becomes an exercise in continuous questioning, learning, and adapting. Instead of worrying because you don’t know the answers, redirect your energy toward asking the questions. Knowing what you need to know is the greater part of the task.
