When a religious, especially one who has pledged poverty, is assigned to a post, he does his best to perform his tasks. When he is reassigned to a new post, he simply moves on, does the same again, not attaching himself to his or her previous accomplishments in any way. This is also the way to live for us lay folks. We see our roles as assignments from God. We do our best to please him. When we are done, we are happy and move on, not attaching ourselves to what we've done because it's just an assignment from God. This way we'll always feel free and peaceful.
