outreach = value * trust
if trust is 0, no matter how good the product is, no sale.
if value is 0, even your own family will not purchase.
But we all understand value considering our schooling, what is harder for us to understand is trust. We are much more intellectual than the average person, so we tend to think that people value and trust their own logic. We are much nerdier than the average human, so we tend to assume people choose products based on how interesting it is. Sadly, they don't:
trust = history * UoMe
if you have a lot of history with someone & you are not indebted to them, they most likely will buy.
if they don't know you & they owe you nothing, they won't buy
You are making a huge pile of assumptions about who "we" are. This is a pile of statements you have learned about yourself. But you are missing the fact that everyone is different. If this formula and way of thinking works for you, great. Thanks for sharing it, maybe someone else will gain some insights as well.
But you are not speaking universal truths here, you are speaking personal lessons.
