The activity no longer becomes something seen as a means to an end and it becomes something an individual wants to do. This can be seen as someone who likes to run for the sheer joy of running and not because they need to do it for exercise or because they want to brag about it. Peak flow can be different for each person. It could take an individual years to reach flow or only moments. If an individual becomes too good at an activity they can become bored. If the challenge becomes too hard then the individual could become discouraged and want to quit.
