The main thing is to keep the main thing the main thing. The problem is that the main thing is a moving target and changes. What is the main thing today may be “so last year” by next week. Two things are required to manage this volatility. First, clear core values, i.e. a solid understanding of what is truly important to you (personal) and the organization (corporate). Second, ruthless re-prioritization, i.e. constantly asking what is the most vital thing that I need to do today.
