Quote from FuturesTrader71:
I see more similarities between poker and trading. They both require the same hard work, knowledge and discipline. How much hard work? Well.... that depends on how much you love it.

Quote from illiquid:
I'd say any trader who readily accepts unknown outcomes, whether he calls it gambling or not, is far better off than the trader who is so stubbornly sure of his views or methods that he feels insulted by being called a "gambler". Beyond that, it's a matter of semantics.
