I like this part the most, it justifies why not all people want to play Poker full time for their entire life! "The largest downside to poker that I can vouch for is a lack of fulfillment when it comes to feeling constructive and productive. Some people gain fulfillment from the inherent challenge of playing the game, others not so much. Anybody who can battle the competitive arena of poker and come out ahead has to have some inherent creativity, creative energy, or just mental wherewithal in general. And my biggest criticism of the poker community at large is that I often looked around and saw a bunch of driven, bright individuals, duking it out over card games, who could easily be the best at other things and making huge impacts in other avenues of life: discovering vaccines, solving debt crises, opening small businesses, finding homes for puppies. All the competitive vigor could easily be channeled towards something that makes the world better off".
