Many times we received good or bad intentional advice from our family, friends or colleagues which are peppered with conventional wisdom. Advice such as what course to study, how to study, career advice etc will always be given irregardless if you asked for it or not. The strong willed person (some say stubborn) will not be easily swayed and be able to stand up for themselves but the more easily persuaded person will tend to go with the crowd. I would like to point out certain conventional wisdom that is not so wise in investing or personal finance.
