Maud posted this great advice from Joan Didion in Slouching Toward Bethlehem, a collection of essays published almost forty years ago:
If we do not respect ourselves … we are peculiarly in thrall to everyone we see, curiously determined to live out — since our self-image is untenable — their false notions of us. We flatter ourselves by thinking this compulsion to please others an attractive trait: a gist for imaginative empathy, evidence of our willingness to give. Of course I will play Francesca to your Paolo, Hellen Keller to anyone’s Annie Sullivan: no expectation is too misplaced, no role too ludicrous…
It is the phenomenon sometimes called “alienation from self.” In its advanced stages, we no longer answer the telephone, because someone might want something; that we could say no without drowning in self-reproach is an idea alien to this game. Every encounter demands too much, tears the nerves, drains the will, and the specter of something so small as an unanswered letter arouses such disproportionate guilt that answering it becomes out of the question. To assign unanswered letters their proper weight, to free us from the expectations of others, to give us back to ourselves — there lies the great, the singular power of self-respect. Without it, one eventually discovers the final turn of the screw: one runs away to find oneself, and finds no one at home.
Maud offers it as advice to writers with day jobs, but I think it's broader advice to those of us in helping professions.
