I strongly believe that missionaries make better products. They care more. For a missionary， it's not just about the business. There has to be a business， and the business has to make sense， but that's not why you do it. You do it because you have something meaningful that motivates you.
I ask senior leaders to not do anything unless they're willing to do it for 10 years.
If you only do things where you know the answer in advance, your company goes away.
