Irrationality & rationality. What i learned about reading '48 laws of human nature' written by the author Robert Greene. Keep an eye out for irrational people. As they are emotional reactive in general, they tend to make others around them more anxious. Be more rational. Look at people their past patterns, their achievements and specific competence instead of their 'charm' or 'appealing personality. Never take a person just as he/she looks like from the front. Also, be a listener instead of a talker.
