Self awareness

'The Five Essential Leadership Questions" by R. John Young suggests that before we can truly know others we must know ourself. He suggests that cultivating self-knowledge is critical to becoming a trusted an effective leader.

Self knowledge can increase our self-certainty or our self-confidence. Self-certainty is associated with both higher self-esteem and a greater sense of personal control...

It is often our intuition that guides our thoughts and decisions. Self-knowledge is the cornerstone of intuition. We know either by science, faith, or intuition. But intuition is hard to define. It can be understood as knowing without being able to understand or describe why we know.

People with strong intuition seem to have immediate knowledge about a fact, or truth, as a whole and the awareness of past, present, or future events without the conscious use of such processes as linear reasoning, rationality, or analytics. 

Rationality is a systematic way of thinking that generates a number of linked propositions that can be converted into assumptions and theories about truth.

The greatest value and higher form of logic is the inter-relation between intuition and rationality.
