Rather than looking at how lots of different people have experienced flow, Know to Flow is about my own experience of flow across a wide variety of activities. They range from motorcycle riding to Chinese calligraphy but also include 20 years of teaching (plus a few more of doing) yoga.
These experiences by themselves aren't enough to make me an expert on flow. I've spent a lot of time trying to understand flow and its opposite mindstate. And part of that understanding comes from having been an engineer as well as an armorer. In both instances, I've learned to understand the things I was working on and to fix them. How does this relate to the idea of flow? You could think of a problem as a lack or inability to flow. Anytime we have a problem, that's when we need to use our thinking mind (particularly if we don't have the necessary experience or understanding to know what the problem is.) When we solve problems, then we can flow, if we choose.
Going beyond the usual recipes or prerequisites for getting into the flow, this is how an everyday person gets into the flow easily.
This isn't to say that you can't learn from skilled people.
It's to say that anybody can access the flow mindstate and you don't need extreme activities or experiences to get there.
And have you ever heard that Bruce Lee talk about "being like water"?
With Know to Flow, you'll learn how you can be like water. (And why you can't be like water in space.)
Plus you'll learn one possible definition for "efficient learning" and how you can make your own learning more efficient.
