To use your line of reasoning, let's take another anomaly: Steve Jobs. The dude was adopted, was a community college dropout and did a ton of drugs. He woke up one day at 42 and found himself back at the CEO position of the company he co-founded and now he's considered by many the most successful CEO of our time. His company has a market cap of $300 billion+ and has created a whole lot of other intangibles by surrounding himself by other great people who love what they do.
Creativity and passion is not something you can teach your child--much less beat into them (this actually achieves the contrary). But yes, that doesn't mean some discipline and other blahs aren't important.
