"The best revenge is massive success." Frank Sinatra
An unhelpful quote is one that doesn't help the reader recognize their wholeness, a fairly predictable result when the author is unable to see their own.
Here's what makes this quote unhelpful...
It's predicated on revenge and rooted in fearfulness
It's not only revenge but the "best" form of it
It stems from a scarce mentality that feels need to prove
Success is something you do to rather than with someone
In order to win, someone else must lose
My sense is the author suffered one of the universal, archetypal wounds of shame, abandonment, or betrayal by someone he trusted, cared for, and confided in. His ego's attempt to settle the score and regain moral superiority seems to have come through the narratives associated with status, power, and control: I'm better than you, and therefore you cannot hurt me.
A simple reframe frees the author, the party who hurt him and all who consume this quote: "The best form of healing is extending massive grace."
