Though I don’t know if he actually said it, Abraham Lincoln is quoted as saying something like, “You can please all the people some of the time and some of the people all the time but not all the people all the time.” Over the years, I’ve developed a theory, much like the quote, that has never failed me. A leader who is loved by all is probably not an effective leader. A leader who is hated by all is also most likely ineffective. A leader who is loved (or at least liked) by most but disliked by a few is probably the most effective leader.
