The ten thousand hour principle states that after you put 10,000 hours into anything you're an expert. I have 10,000 hours of experience creating Comedy RPG game systems. I made my first game when I was 8 years old (A Legend of Zelda tabletop game called Gannon's Bad Day) and in the last couple years professionally developing the first two DQ games. I have 10,000 hours invested in Business Management (Game Industry and Newspaper Media) Not quite 10,000 hours of drinking yet but close :)
