PLAN. COMMUNICATE. LEAD.
Whatever you do does not have to be perfect, but it has to be good enough to move ahead.
Time is always the limit. What is important now, might not be important tomorrow or a week from now. While you are working on your perfect plan, others move ahead with next and next steps. And by the time you are ready with your excellent plan, it might turn out to be useless. And that would be a waste.
