"After more than twenty years as a transactional trader and businessman in what I called the "strange profession," I tried what one calls an academic career. And I have something to report--actually that was the driver behind this idea of antifragility in life and the dichotomy between the natural and the alienation of the unnatural. Commerce is fun, thrilling, lively, and natural; academia as currently professionalized is none of these. And for those who think that academia is "quieter" and an emotionally relaxing transition after the volatile and risk-taking business life, a surprise: when in action, new problems and scares emerge every day to displace and eliminate the previous day's headaches, resentments, and conflicts. A nail displaces another nail, with astonishing variety. But academics (particularly in social science) seem to distrust each other; they live in petty obsessions, envy, and icy-cold hatreds, with small snubs developing into grudges, fossilized over time in the loneliness of the transaction with a computer screen and the immutability of their environment. Not to mention a level of envy I have almost never seen in business. ... My experience is that money and transactions purify relations; ideas and abstract matters like "recognition" and "credit" warp them, creating an atmosphere of perpetual rivalry. I grew to find people greedy for credentials nauseating, repulsive, and untrustworthy."
