Serves their best interests, and in so doing will not always be popular, may not always impress. But because true leaders are motivated by loving concern rather than a desire for personal glory, they are willing to pay the price.

Custodians hold something in trust on behalf of others.
It is not a behavior motivated out of self-interest. A custodian then, is an individual who upholds what is best for all people even if it may not be in their own interest to do so.

This is an attitude of mind that focuses on the task at hand and not on what the leader may gain from the position. This idea seems at odds with what we see happening around us today.
