They are two forces that rule everything you do.  Pain and Pleasure. Included in Stoic Philosophy in 300 BC, it's three rules are easy to understand and apply: 1)  Most decisions you make and actions you take have the goal of attracting pleasure into your life. 2)  When things get challenging, decision and actions become focused on avoiding pain.  Your mission is to get back to pleasure. 3)  Avoiding pain will always overrule seeking pleasure. Before you take action, acknowledge what is driving your behavior.  It won't be long before you find yourself living in the pleasure zone.
