Director and Thinker: The Work-Mode Personalities
A long time ago a company I worked at decided that being a Relater (a Dove) was the worst personality to have. I think that judgment is wrong, and I think the whole idea of ranking personalities is wrong. Personalities are contextual: they change with the room you are in and the season of life you are in. But there is a work personality you can learn to switch into, and for engineering the Director and the Thinker are the two worth practicing.
