Value is were you ask yourself, is the task at hand worth doing or not. More specifically, you will find yourself asking: what will I gain from doing a task? why should I spend time doing such a boring task anyway? or even why is it important I do this task in the first place?
In short, there are 3 different forms of value you can find in doing a task: Gain, Joy AND Importance. These values are all explained in further detail under the tabs above.
