Poker has taught me so much, especially when I became a full time pro.
I believe poker is a microcosm of life. A lot of the lessons you learn in this game are also very important in all aspects of your life.
This game has taught me for example, the importance of a strong work ethic, emotional control, maintaining a healthy lifestyle (diet, fitness, sleep maximization), staying focused on the long run, not chasing fame, staying humble, always continuing to learn.
And so much more.
