The best leaders (heck, the best people) I know have a couple of questions running continually in the back of their minds:
How am I making this situation, this team, myself better?
How am I NOT making this situation, this team, myself better?
As answers to both questions gain clarity for these folks, they then purposefully do more of the former and less of the latter. Intentional bettergetting.
Note to self: Don't try this unless willing to engage in self-changing strategies.
