The fundamental mismatch error
"It's me, not you."
vs.
"It's you, not me."
What happens when you're unable to serve a customer well, or engage with an employee, or work with a partner?
One instinct is to blame the other person, that your art doesn't match their expectations, and they ought to change, or leave.
And the other is to put the blame on oneself, to state that, "it's up to me to change to make them happy."
Either might be true.
For some people, that's hard to swallow, but it's true.
If you're not getting what you seek from the work you do, it could be because your instinct is to go too far in one direction, a belief that doesn't help you very much.
Blame too many other people and you become a lonely diva, bitter and alone.
Blame yourself too often and you become a wishy-washy panderer to the masses.
Mismatches have to happen. The opportunity is in dealing with them in a way that leads you (and your publics) to the place you want to go.
