Strange though it may sound, good enough sometimes isn’t good enough. Very often people are so busy that they will settle for getting things done to just about an acceptable standard and then start to focus on the next task, rather than get the first thing as far beyond ‘just good enough’ as possible. What we end up with then is mediocrity at best.
There is a technical term for this: satisficing. This is a made-up word, derived from combining satisfactory with sacrificing. It refers to the tendency for people to settle for what is satisfactory and thereby sacrifice producing the best results possible. Freud captured this idea when he said that the good is the enemy of the best, by which he meant that we can so easily fail to fulfil our potential by not looking beyond what is good enough.
