Go with the Flow

This is a very interesting read on the concept of THE FLOW. Apparently it is theorized by someone attempting to describe or quantify what happiness is for people in general. Though in this context its talking about computer games, it actually does apply to every aspect of our lives.
In a nutshell, if we don't have enough challenges to challenge our abilities, we get bored. however if we have too much challenges for our abilities, we get anxiety. So a good place to be in would be when challenges match our abilities. For humans however, they found that there's a gray area that expands this "good place" so that humans can accept a rather small level of anxiety or boredom from time to time.

interesting no? :)
