What attribute correlates most strongly with career success?

People often point to externals – an ivy league education or a well connected family member. Occasionally, they’ll cite internal aspects – an abundance of talent, chart-topping intelligence or an immutable work ethic. The more nihilistic might chalk it all up to luck – just being in the right place at the right time.

Without question, all of those factors will help, but none of those will get you anywhere without the right frame of mind.
