This document discusses self-management and different aspects of understanding oneself. It defines four ways of understanding oneself: assumed self, manifest self, objective self, and requisite self. It explains that there are often gaps between these different selves that can be minimized through habits like being proactive, beginning with the end in mind, putting first things first, thinking win-win, seeking first to understand then to be understood, synergizing, and sharpening the saw. Developing these habits can help align one's different selves and understand oneself more fully.
