I agree with Chris Corrigan:
Somehow, the view of learning in the world has been confused with the kinds of quality control that is attached to manufacturing. We imagine that a learning experience will have specific achievable outcomes and that upon completing a course we can be certified in the competency in which we have been trained. While this can be true for technical training, such as how to operate equipment, with things like art and strategy and leadership and communications and other practice based arts, the opposite is actually true. When I leave practice based learning events I recognize that I am a baby, just starting out, and with a lifetime of practice ahead of me.
