Joan Didion's essay, "On Self Respect", is an excellent read.

You can find it here.

Some nibbles to entice you:

"The dismal fact is that self-respect has nothing to do with the approval of others – who we are, after all, deceived easily enough; has nothing to do with reputation, which, as Rhett Butler told Scarlett O’Hara, is something people with courage can do without."

"In brief, people with self-respect exhibit a certain toughness, a kind of mortal nerve; they display what was once called character, a quality which, although approved in the abstract, sometimes loses ground to other, more instantly negotiable virtues."

"To have that sense of one’s intrinsic worth which constitutes self-respect is potentially to have everything: the ability to discriminate, to love and to remain indifferent. To lack it is to be locked within oneself, paradoxically incapable of either love or indifference."

"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."
