A strong-willed mother can be found behind many famous people. Or at least that was one of the findings in https://www.amazon.com/Cradles-Eminence-Childhoods-Famous-Wo.... (A book I'm familiar with because my mother read it and applied its lessons in odd ways to her parenting..)

That is why on general principle I would expect his mother to likely be a cause for his success.

The resources needed are less than you would think. A child raised with specific kinds of support and challenges is more likely to have an impact on the world than one raised with every advantage. You can get an idea of the useful kinds of challenges and support by looking at the childhoods of actual successful people.

http://www.amazon.com/books/dp/0910707561 is a good source of insight based on it. However I would humbly suggest that consciously attempting to follow some of its advice would be legally actionable.
