People are paradoxically more likely to engage with something meaningfully if you don’t try to tell them it’s meaningful.
Telling someone “this drink is a miracle elixir that will change your life” will cause them to dismiss it. Telling someone “this drink is pretty good and once or twice a month it can really clear up digestion issues” then that’s a verifiable claim in the realm of reality. It can be engaged with. And if the drink is good and has good health benefits, people will drink more of it!
The point is, overselling comes across as lying, even if the claim is totally true. Ease people into things, let them come. Even if what you have is life-changing, you can’t change everyone’s life overnight.
