Elon Musk: How to Become an Expert in Any FieldThe co-founder and CEO of Tesla has one key strength most of us should put into practice.

Musk's statement goes against much traditional advice that in order to become successful, you have to specialize and become proficient in a single field of expertise. "The jack-of-all-trades is master of none," goes the old adage. And yet Musk has proved numerous times that it is not only possible but profitable to generalize.

It is important to view knowledge as sort of a semantic tree -- make sure you understand the fundamental principles, i.e., the trunk and big branches, before you get into the leaves/details or there is nothing for them to hang on to.

As a modern polymath, Elon Musk demonstrates that studying widely across many different fields of knowledge can give you an information advantage that fuels innovation. Musk is able to integrate unique combinations of skills and knowledge and transfer his learning across disciplines. 
You might not have the time or energy to devote 85 hours a week to honing skills and knowledge, but it's still worth investing a little effort to branch out. The beauty of being an expert generalist is that it's most likely easier to achieve and more rewarding than becoming a leading expert in just one field.
