Infection: avoid the unhappy and unlucky: you can die from someone else’s misery — emotional states are as infectious as diseases. You may feel you’re helping the drowning man but you are only precipitating your own disaster. The unfortunate sometimes draw misfortune on themselves; they will also draw it on you. Associated with the happy and fortunate instead.
Personal accountability prevails. We are responsible for our actions. I will not stress over another’s poor decision making skills, but I will do my best to isolate the bad apple from the good.
