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.
We've done price elasticity studies, and the answer is always that we should raise prices. We don't do that, because we believe -- and we have to take this as an article of faith -- that by keeping our prices very, very low, we earn trust with customers over time, and that that actually does maximize free cash flow over the long term.
There are two ways to extend a business. Take inventory of what you are good at and extend out from your skills. Or determine what your customers need and work backwards, even if it requires learning new skills.
