I would argue that mediocre things play a critical part in all happenings. While bad things should undoubtedbly cease, and good things should continue (or indeed increase, but subject to conflicting findings in future study), the mediocre things should maintain their current course. This, because without mediocre things, all things would be good, thereby diluting the effectiveness of good things, and rendering them mediocre. Some may argue that mediocre things will become bad, which may in fact be the case, but at that time the process should be reapplied, ensuring a very bright future indeed. Unless that future study shows otherwise. Meanwhile, optimism and pessimism should be calibrated according to the beliefs of the individual... and pessimism will really be the portender of mediocre things, as bad things will have gone away. I suppose I should do my part in helping end all bad things, by ending this post abruptly, if awkwardly.
