Very true @czechglobalhosts. Perhaps I am biased, but through the study of the arts, specifically music, one puts this philosophy to practice on a daily basis. In the creation of art people MUST analyze their 'failures' to figure out how it can be avoided in the future and/or use these 'failures' as a jump off point for new unique creations. Again, I am biased, but through concentrated work in the arts individuals can explore this idea and learn to adapt it to other aspects of their lives.
