Experiential learning
Experiential learning is all about doing. Management is not a theoretical craft. It may have lots of different theories and frameworks behind the science, but make no mistake about it: management is ultimately all about execution and application in the real world and with real people.
The importance of trying, and possibly failing, and then trying again cannot be underestimated. Most seasoned and self-aware managers will be able to tell you their "war stories," or times where they have crashed and burned, but also examples of victories, large or small. These war stories are invaluable experiences that they have gone through, which have shaped them up to the point you see them at today and will continue to going forward.
To maximize experiential learning, you need to simply maximize your experience by being open to defeat and willing to try, and try again and again, if necessary.
