I&#x27;d be curious to hear from employees who have worked for Elon Musk either at Tesla or SpaceX. I&#x27;m currently reading Ashlee Vance&#x27;s book on Elon and the descriptions of the working conditions for Tesla and SpaceX employees sounds both exhilarating and completely exhausting.<p>Does working on something as truly world-changing as space travel or electric vehicles make up for the 80+ hour work weeks? Is it easier to work so hard when there&#x27;s no doubt that what you&#x27;re doing matters?
