RP - You mentioned risk in your last sentence.
There's two types of risk...Human beings generally focus on "downside risk" to use a financial term. The risk that an investment will go down in value.
Our relationships are investments.
The other side of risk is called "upside risk" - Which is the extent to which the value of an investment may increase beyond forecasted levels.
I sometimes like to think about that...as we generally see "risk" as a negative. But we only take risk as there are opportunities for positive returns.
And it's not too much like playing the stock market ! But you do have control over who you invest in
