Word-of-mouth beats paid channels

Your mindset should almost be like you're trying to create a word of mouth machine. If you can get that part right, everything else becomes significantly easier. And if you have any, and I think this applies to both prosumer, B2C, as well as even B2B products, if you have a B2B product, even if you're not telling all of your friends, you should be telling colleagues where that product is relevant.

There has to be this almost irrational, emotional response to your product. People internally have to authentically love something to really stand behind it. But externally too, if people can sing at the top of their lungs about how great your product is, that's a wonderful place to be.

Quality is growth. And if you think about how you can make your product easier to use and more understandable, that will of course drive people to use it, and use more of it, and have a better experience with it that they'll want to talk about with others.

Before the referral program, Dropbox had amazing referral rate. Companies that are trying to copy it are like, 'Why isn't anyone talking about a product? Let's add a referral program with incentives.' To me, I think it's a great accelerant when it's already working, but it can't fix it if people don't want to talk about your product.
