Is experience a better source of knowledge for the investor than book learning?

[i4value]

Investing is a skill. To develop this skill you need the concepts and practice. The former is what you call book learning. The latter is experience.
 
While I emphasize practice, without the concepts you will just be getting the wrong experience. You might as well invest blindly.
 
It is like asking whether the brain or heart is better for living. It is a misleading question as you need both.
 
Now if the question was whether to emphasize concepts or experience, the answer would be more relevant.
 
Do remember that the concepts were established based on someone's experience.
