Arthur C. Brooks

We might call this the “principle of psychoprofessional gravitation”: the idea that the agony of decline is directly related to prestige previously achieved, and to one’s emotional attachment to that prestige. If you have low expectations and never do much (or do a lot but maintain a Buddha-like level of nonattachment to your professional prestige), you probably won’t suffer much when you decline. But if you attain excellence and are deeply invested in it, you can feel pretty irrelevant when you inevitably fall from those heights. And that is agony.
