It must be some obscure law of nature

… whereby when I have the least time to spend on a particular task, there is an ordering of requests that I maximize the time spent on that task using the least efficient mechanisms possible.
Put another way, when I am busy, more people seek more of my time to handle things that I shouldn’t need to be involved in.
Or another way … simple things should be trivial, complex things possible, and yet the universe appears to arrange it self so that simple things become complex, and complex things become impossible.
Which I am fairly sure is somehow a restatement of the second law of thermodynamics in some form.
