"Buy wisdom, do not sell it." ~ Holy Bible
To be 'learned' is to have lots of information.
To be 'wise' is to have context .
Lots of information without the correct context is meaningless.
A trader who spends time learning the ins and outs of the stochastic indicator has knowledge.
But he lacks the wisdom to see that the market is non-stationary. He has the incorrect context of the market. So he will go on trying to investigate using stochastics with different parameters on different time frames, with no results.
A more general example is - an individual who gathers information and knowledge as to how to become a CEO. He is learned. But is he 'wise'? A wise individual has context - wisdom says that you will only be happy when you do what you love. Will being a CEO make him happy?
The interesting thing is, for someone to get additional information is easy.
But for someone to change his context (gain wisdom) is difficult. Try to tell someone that he should not be a wage slave (even though he is making 6 figures), and that he should follow his dreams. He will look at you like you are crazy.
