Many years ago I had the privilege of working with my father at a company that manufactured machine tools. Dad and I worked very little together but on one project we found ourselves in many design meetings essentially working for a guy Dad did not particularly like. I could tell that by how my father held himself occasionally while in the meeting this gentleman was talking about various ideas. When I asked my father about it he said that you always have to listen to the other guy even if you think he is a jerk because it is possible that he might have a good idea.
That thought has helped me through many uncomfortable conversations where I might have rejected the other’s opinion or thought simply out of hand because he rubbed me the wrong way.
I could have rejected my Dad’s lesson but I decided to keep it for my own.
