If working less is so productive, why is it so hard?
Mike Fishbein

Truth is, when you have to complete a task then you have to — but how long you take to do it depends on you. If you focus on the task at hand then it will take less time which means you will be able to complete more tasks faster. How do you focus on the task at hand? By making a list of tasks, prioritizing the most and least important tasks and then cracking on. Then follow your list so that your mind does not get a chance to get the better of you.
