Relationship Over Excellence
Sometimes in the search for quality and excellence, we sacrifice kindness and grace. Instead of putting others ahead of ourselves, we put the goal, the target, above all else. Even if that means trampling over bodies to get there.
Yes there needs to be drive, motivation, and a clear goal, but never should those take superiority over another person. If you must make a choice between excellence and relationship, always lean towards relationship. Quality in execution will be appreciated temporarily, but a damaged relationship will be scarred for life.
