To the previous poster:
There isn't much thinking involved in poker until you get to high stakes, where bluffing and counter-bluffing are commonplace...
Because I want to play in a straightforward way, I prefer to multi-table mid-stakes.
The only "thinking" involved is the initial few weeks of strategy formulation, before you start playing in any significant manner.
There are only two ways to make money in poker
1) to play tight and aggressively
2) to play relatively loose (but not too loose) and aggressively
The key underlying theme is to play aggressively -- the trading analogy would be to have liberal position sizing of say 1% of your account and to pyramid when things are going for you...
I prefer to play tight (have a limited number of hole cards that I am willing to commit money to). Since I am multi-tabling and since I am playing the premium hole cards only, when I hit my hand, I often take down an opponent's entire stack.
The problem with playing loose is that you must have good opponent hand reading skills, whcih is possible when you are playing 1 or 2 tables, but becomes impossible when multi-tabling...
The way I play, I make lots of small losses, an equal number of small wins, a handful of big losses and a significantly larger number of big wins... in terms of distribution of gains/losses, this is not too dissimilar to how things were when I was trading...
The beauty of poker is that it is more easily summarized in terms of $ per hour. I simply couldn't do that in trading, since I was at the mercy of market conditions, and would make most of my profits in a handful of months... and in the dry months, I would sit there, become demotivated and basically pissed off...
What I do now is play poker 5 hours a day (including weekends) for income generation and put on perhaps 5 position trades a month for speculative capital growth...
