Good
leadership involves responsibility to the welfare of the group, which means that
some people will get angry at your actions and decisions.
It's
inevitable, if you're honorable. Trying to get everyone to like you is a sign
of mediocrity: you'll avoid the tough decisions, you'll avoid confronting the
people who need to be confronted, and you'll avoid offering differential
rewards
based on differential performance because some people might get upset.
Ironically, by procrastinating on the difficult choices, by trying not to get
anyone mad, and by treating everyone equally "nicely" regardless of
their contributions, you'll simply ensure that the only people you'll wind up
angering are the most creative and productive people in the organization.
