What?
Being able to "coach" is why they get paid the millions. Being a "nice guy" is an expectation of everyone walking down the street.
My dad is a normal guy. Always smiles and never acts mad in public. He lost his farm in the 80's, he lost his passion and dream. He had no choice but to try and save it by taking on two extra jobs to no avail. He then ran for County Assessor, a job he hated, but knew he was more than qualified for. He did that for 16 years and outside of the people he worked with, I swear he hated every second of it. But no one could have told you that. He then took on a job as a network administrator for the local bank because of his personal relationships. Again putting in long and unappreciated hours. He is my Dad and a "normal" guy to most.
Being nice when facing adversity isn't a "bonus" it is an expectation for a person in civilized society. It's the people that "give up" is who we tend to look down on, not as peers.
