Want to become a billionaire?

I thought this list from the Harvard Business Review of company mission categories was inspirational:

1. Making the world more beautiful.
2. Making the world more fun.
3. Making the world more efficient and smart.

They go on to highlight some billionaires whose companies fit those categories. They all fit my personal mantra (which I think I stole from Justin Rosenstein of Asana but I’m sure he doesn’t mind) which is “have a positive impact on the world.”
