Quote from illiquid:
I'll one up you: how many occupations are there in the world where you need absolutely no one else to earn a paycheck? Of course traders need other traders in aggregate ie, the market itself, but name another profession where you can say "fuck off" (and mean it) to each and every person you meet for an entire year -- and still get paid?
Good point!
Another one - trading is almost the only occupation where all you have to do is be right (on aggregate) and then implement your opinion to make money. There are countless jobs where you can be 100% right, tell everyone - and either they don't listen, or even worse you get fired. A year or two later when reality proves you are right, you don't get a bonus and probably won't even get your job back. Trading is the only field where even if everyone in the world thinks you are wrong, being factually right is guaranteed to make you money.
