I don't know if they're totally at odds if you separate your ambition from your identity and sense of self-worth. I live in a fairly constant state of discontentment (maybe as a symptom of ambition), but when I step back and self-evaluate I rest easy.
A steady state of always feeling peace in the background seems pretty impossible though under any circumstances.
