What they call “play” (gym, travel, sports) looks like work. - Nassim Nicholas Taleb

Any book not worth rereading isn't worth reading.

You can tell if a discipline is BS if the degree depends severely on the prestige of the school granting it. I remember when I applied to MBA programs being told that anything outside the top ten or twenty would be a waste of time. On the other hand a degree in mathematics is much less dependent on the school (conditional on being above a certain level, so the heuristic would apply to the difference between top ten and top two thousand schools). The same applies to research papers. In math and physics, a result posted on the repository site arXiv (with a minimum hurdle) is fine. In low-quality fields like academic finance (where papers are usually some form of complicated storytelling), the “prestige” of the journal is the sole criterion.

It is immoral to be in opposition to the market system and not live (somewhere in Vermont or Northwestern Afghanistan) in a hut or cave isolated from it.
