Boz on some learnings at facebook:
Being kind is fundamentally about taking responsibility for your impact on the people around you. It requires you be mindful of their feelings and considerate of the way your presence affects them.
Being kind hasn’t hurt my effectiveness at all. Being thoughtful about the emotions of my colleagues hasn’t made me any less right or wrong, it has simply made me more likely to be asked to help in the first place. Being invited to more conversations has allowed me to scale my impact in a way that would have been unfathomable on my own.
