Learning from a good experience is an overwhelming experience, but learning from a bad experience is certainly not the best way of getting to know about something --it wastes time, effort and resources, and on top of that you have to deal with loss or depletion of energy and emotional dilemma. Learning from other people's experience might be beneficial, but learning by going through the same mistakes which had been made by other people is certainly not the best way of learning.
