Really good advice. Interestingly, the skills of controlling your emotions and rolling with the next card are also vital skills for trading. That's why a lot of old-school traders recommended that newbies take up poker before getting into the game.
Fun Fact: When he was in the Army, Carl Ichan won thousands of dollars playing poker!
That's a cool fun fact, did not know that.
I certainly noticed the similarities between poker and trading, particularly being on twitter and following 100's traders of all levels of talent/honesty. The key is to absorb as much useful information as possible in order to act in a productive way. Just like poker, there's a lot of information. But learn the charts, learn the fundamentals, get the basics of the "game" down, then start building off of that base of knowledge by finding signals in the noise.
