A one at the end of the year is the Sun, the sign of leadership. But of a particular kind of leadership: not the kind won through a post and through pressure, but the kind people follow of their own accord.
A person under the Sun leads by the way they live rather than by giving orders. They do things the way they consider right, and that turns out to be enough for people to appear alongside them who want to live the same way. Issuing a command usually comes to them less well than setting an example.
The difficulty lies in what it demands of them. Leadership of this kind rests entirely on consistency: the moment a person begins to say one thing and live another, the influence is the first thing to go, and winning it back is harder than earning it the first time.
