Not groveling, not submissive. Just empty of self, empty of judgment, accepting of all events.
Acknowledge reality without glee or remorse, and move on.
Gary Vaynerchuk’s videos are full of the need for humility. He talks about it as meaning without care for others’ opinions. That’s a good view, too. If it needs to be done, do it. Opinions (yours or other people’s) don’t come into the equation.
