There's an important point not empathized enough in this article: Supportive Parents The lack of support from your parents is probably the biggest brake you may have at this age. Fortunately for this kid, thanks to the support of his parents, he managed to succeed in a really short time. Kudos to the entire family.
Does it say his parents were supportive? It mentions they leant him money, is that what you meant.
It says his mother helped him make a website to sell the wheels. That's pretty substantial, and surely his parents signed some contracts along the way to get deals done (which means money and time, not to mention the more ethereal "support" that you give someone when you sign a contract for their benefit and your possible detriment).
