"I'm a quick learner" is a cliche.
My job for most of my career has been to adapt software and practices to varying standards.
I show up in a new town, in a new state, and provide solutions for a wide arrange of needs and constraints. I have to provide value very quickly as a typical visit is seldom more than a week long.
A great deal of what I do with new undocumented software is reverse-engineer patterns from behavior. This is time consuming. So much so that I dedicated a career to preventing others from having to work so inefficiently. When I work with people who know what their doing, it feels like magic to me. Adapting to clear instructions is a delight.
