Can leaders gain wisdom without years of experience?

I have created and given a presentation on how to accelerate the development of young leaders.

Drawing on the work of David Rock, Bruce Tulgan, Daniel Goleman and others, I created a model called ABC – for Alliance, Brain Development and Context – that outlines how to help young leaders mature so they can move into leadership positions.

Here is the slide deck (minus the case study).

What do you think? Do we all have to learn about life the hard way, or are there things that can help us mature more quickly?
