In my experience, there's a strong correlation between aptitude at video games and success. This is just my small, possibly skewed sample, but my closest friends I've met through playing WarCraft 3 as a teenager at a competitive level all became high-income, successful, happy people, usually in tech or finance.

I whole-heartedly believe playing video games early on helps nurture a strong competitive drive, discipline, and self-motivation. It probably depends on the game, too. I was playing Civilization II as a 9 year old, played strategy games like StarCraft and WarCraft competitively as a teenager, and eventually played online poker for a living. I don't know if simply playing Candy Crush would yield the same results.
