being Emotionally street-smart: Using Emotional Intelligence in day-to-day life

How does Human Mind work? We all have our own micro-theories to explain; how do people make decisions, how to predict who would do what & when, how do people behave and why, what are emotions and how to deal with them, how to live life in 'best' way possible... But there's always something missing, the dilemma to listen to heart or brain, the sadness in spite of having everything one aimed for, lack of motivation to work for the 'obvious' target... Being 'Emotionally street-smart' is an expression that represents gaining emotional intelligence and using it in day-to-day life.
