My first assessment
I often make this mistake when hiring people. I keep thinking about how they disappointed me in the job, then realise I did not assess them correctly. I placed an expectation on the person and later blamed them for the gap.
I think of a zoo. I accept the nature of a snake or a scorpion and keep my distance. With people, I can start imposing the behaviour I want.
My example is hiring a short person and then blaming them for being short. The thing I complain about was already visible.
I want to get clearer about the person, the particular relationship and the expectations I am bringing. I think accurate assessment matters in business, friendship and the way we live with other people.
