Envy, The Root Cause of Unhappiness

Thou shalt not covet, for gratitude will turn what you have into enough

This means that every candidate will be benchmarked against the quality of all previous interviews, and that you can not recall a candidate you regret not hiring. No matter who you end up hiring, your obvious dilemma is, “what if the secretary I hired is not the best?”
