A term used by the U.S. Military (mostly the Army) to describe knowledge gained the hard way - by making mistakes in combat and fixing them because you have to. The Army has an entire organization, called TRADOC for Training and Doctrine Command, whose job (among other things) is to collect lessons learned and distill them into doctrine and practices.

I want you back, she said.

The process of natural selection hones our genetic material in a way that allows the emergence of new abilities, new designs and adaptations.

What do you mean you want me back? You have your man. You made your choice.

In the same way, within any complex system the ongoing interactions cause the emergence of unexpected features, new, higher levels of meaning that cannot be predicted from the properties of the parts.

Look, I know I made a mistake letting you go and now I want you back. I love you.

The human brain is one of the most complex systems known to man, it is estimated to contain around 10,000,000,000 neurons.

Just like that? You think you can make everything that has happened magically disappear by saying you love me?

Each of these is itself a cell, a highly complex system in its own right. The chief emergent property of the brain is awareness - of others, of self, of the future and the past.

Don't make this any harder than it already is, I thought you still loved me, I thought this is what you wanted.

In turn, the interplay of brains in social situations gives rise to yet higher levels of emergent properties, ones unpredictable in terms of any individual. This common feature of all emergent systems is often overlooked when plans are made. Novelty arises from new combinations of interactions, new ways of relating to each other and to the planet.

There was a time when I did want that. I would have done anything to have you back. But.. things are different now.

And thus we learn...

"First, let me tell you gentlemen that everything contained in this report I am presenting to you today is outright lies and total bullshit."

"Well then, Bjorn, we have nothing further to discuss and our business is at an end."

"Holy shit are you serious?"

Let's rock.

Your fear is there in your eyes, plain to see, you pompous motherfucker. Outright lies and total bullshit.

Let's rock.

This guy named Cyril lives up the block from me. Who the fuck names their kid 'Cyril' anyways.

He's creepy as all hell and walks with a bit of a limp. It is more the kind of limp you get from being the sissy in a hard time prison than it is the kind that comes from having one leg slightly shorter and more bendy than the other. I could be wrong. I often am.

Don't name your kid Cyril. Lessons learned are not needed to be taught again. If you fail we teach them to you all over again. You start from the beginning again if you stumble. Back to the front of the line in the back of the line that is the front for what I am promoting in my new book out this summer.

Let's rock.

Stoned immaculate. Outright lies and total bullshit.

You're not going to be saved just yet. You have to fall just a little bit longer and a little bit further from the place where you began so it will mean all that much more to you that you have lost all that distance and memory. Start from the beginning again. If you stumble you go back to the front of the line in the back of the line that is the front for a whole new perspective.

Let's rock.
