One of the hardest things for a teacher is to know when to keep quiet and when to let go. It is a terrible thing to hold someone back from success, or to insist on sharing credit, or to tie someone to your apron strings. We need to have faith that we have done all we can, and then we need to kick our birds out of the nest.
