Why learn to simplify chaos?
When you simplify chaos, you look at isolated parts of a chaotic system so that you can understand those parts. Apply this to different parts of a chaotic system and it gradually becomes less chaotic. It simply becomes a system, one that you understand.
A chaotic system is a complex system that you don't understand.
It's like first listening to a band and having someone talk about the rhythm guitar (or the bass), which one is which? While you don't need to know the difference in order to appreciate the music, it can make listening more enjoyable when you finally learn the difference. (And it can help you understand, if you ever wanted to be in your own band, what instrument you would like to play.)
So why learn to understand a chaotic system? Why simplify chaos?
You could define chaos as simply something that you don't understand. By the same token, problems are generally a result of a lack of understanding. When you understand the source of a problem you can fix it.
When you learn to understand a system, you can fix problems when they occur.
And while you might not be able to fix all problems, the chances of fixing a problem when you have understanding are a lot better than when you don't (or when you don't know how to acquire understanding).
Two ways to define the word "problem"
A simple way to define a problem is that it is the difference between the current state and a desired state.
Another way to define a problem is that it inhibits flow.
When you simplify chaos you can be on the road to fixing problems.
And you can be on the road to getting into the flow, or allowing flow to occur.
When you know how to simplify chaos, you make life easier, more enjoyable.
It's like having lights turn green as you get to them.
