Those with confidence and certainty, think and act.
Those lacking confidence and certainty, denounce and manipulate.
Confidence comes from the habitual use of one’s mind in a rational, sensible way.
Angry, humorless moralism comes from a mind in the habit of forming rushed, emotional and unreasoned conclusions–and attempting to hold on to them.
A confident mind leads to a confident personality who never wants or needs to control others.
An unconfident mind leads to a personality interested in gaining the control over others that never was accomplished in one’s mind.
You find out what kind of confidence a person has–or lacks–not primarily by what he claims (or proclaims) to be his ideas, but primarily by what he shows himself to be, in practice.
