It wasn’t her job. She just did it.

On Unclear Roles

She makes everything better.
On Unforeeen Obstacles

She recognizes problems and issues before they become big problems and solves them. She doesn’t rely on anyone else to solve her problems.
He can hit a roadblock, figure out a way around it, and keep on moving rather than getting disheartened and slowing down.
She sees things to the end even if she gets no credit.
On Moving Targets
He seeks out new information without being prompted.
She takes feedback as a positive.
She learns quickly from errors.
When I have feedback, she takes it and does something with it. She doesn’t get down, she sees it as a chance to improve.
On Unrelenting Demands
He frequently comes to me and says, “What can I take off your plate? How can I make your job easier?”
She avoids drama. Things don’t get to her. She is compassionate but refuses to be an actor in any soap opera.
She exudes positive energy. It’s just big fun working with her.
