It is an incredibly naive perspective to believe that people should and will work at their best however they happen to feel at work. The corollary delusion is that I think it’s possible because I’ve done my best when I’ve been struggling or miserable. This belief has apparent credibility if we define success as not getting negative attention for our performance. Reality is that we probably we not at our best. Unhappiness shuts down our best and most creative thinking. Investing in everyone’s happiness is a more realistic strategy.
