Why pursue it? Well, two reasons come to mind.
Sure, I may mightily fail and look like the world's biggest fool. Which of course didn't stop me when I set my 2008 sights on the top performers of the industry, or when I gave up a very comfortable executive corporate career over a decade ago to take up this business, but I digress. And Lord knows I've had my share of pratfalls over the course of my 48 years on this planet.
Have a pleasant evening and enjoy the game.
