Efficiency vs Productivity

I saw this post in Medium: https://medium.com/swlh/focus-on-productivity-not-efficiency-4ed4fe9a454f
This has made me realize that a lot of people I know do the efficiency thing more than the productivity thing. Efficiency mostly is doing the same thing only a little bit better while increasing productivity in the expanding mindset means expanding what you do.
I know it is not an exact example but it’s close.
