The more expert you become, the more patience you will need when dealing with nonexperts.
Experts move quickly through an analysis in their topic area to find the subtle problems. Nonexperts will take more time and may still miss the subtle problems.
Experts see way more shades of gray in their topic areas. Nonexperts often miss the nuance.
Experts may have counterintuitive ideas about what to do next. Nonexperts may be confused about the value of those ideas.
The problem?
For the expert, there may be a lot of work just to get a nonexpert oriented in a basic conversation.
The key skill?
Loving patience.
Loving patience with clients. Loving patience with others in the firm. Loving patience with sub consultants.
Your status as an expert may get you hired once, but your consistent loving patience in dealing with us nonexperts will get you hired again and again.
