You don't have to be a genius to learn as fast as Elon Musk. Most people believe that deep knowledge is only for billionaires with special brains, but that is simply not true. To master any new skill in record time, you need to use a simple framework called first principles analysis. This means breaking a problem down to its most basic truths instead of just copying what other people are doing. Whether you are building a rocket like Elon Musk or starting your first company, you have to stop reasoning by analogy and start looking at the raw materials of your success.
