There are many activities in every culture, every time, that exist, activities that are designed to create from. Music, for instance, dance, most of the arts, most of sports exist only to produce flow. And now we have commercialized many of these. But originally they were learned and repeated and transmitted from generation to generation because they provided flow. But that's too easy to find flow in already nicely constructed activities because they are not always there for you to be able to use. So the trick is to do everything that you have to do so as to get as much flow out of it as possible. And that's difficult because most activities are not designed to produce flow. Work, or family life, is often antithetical to flow and the way it's constructed. So you have to make it into flow by focusing on certain aspects of it, finding the challenge in it, and then paying attention to it until you get involved.
