People are vectors

Tom Mueller on SpaceX's early days: 
If people were negative, they were not in the next meeting.

Elon was technically very strong, even though he was just learning about rockets. 

The one thing I noticed, if people were negative, they were not in the next meeting. 

He said, a company is a bunch of vectors. Each person is a vector and they need to point in the direction that you want to go. 

Bureaucracy and office politics and low morale, it's almost random vectors. 

He was always about making all the vectors which are all the employees pointing in the right direction. Forward, moving forward.
