I have ingrained sexist attitudes from my mother. What should I do?

She's not a bad person and was very good to me growing up but from what I saw and heard her say she made being born a female seem like the short end of the stick and there was an implication that I was lucky to be a boy mostly referring to girls being unlucky for having periods, mood swings, breasts, and eventually pregnancy. She also was more lenient with me and my brother than my sister. Now I have a gut reaction pity for women because they're women even though I know it's stupid and I feel that it has set back my relationships throughout my life.
