"Lean In" is intended for professional women to help them achieve their career goals and for men who want to contribute to a more equitable society. The book argues that barriers are still preventing women from taking leadership roles in the workplace, barriers such as discrimination, blatant and subtle sexism, and sexual harassment. Sandberg claims there are also barriers that women create for themselves through internalizing systematic discrimination and societal gender roles. Sandberg argues that in order for change to happen women need to break down these societal and personal barriers by striving for and achieving leadership roles. The ultimate goal is to encourage women to lean in to positions of leadership because she believes that by having more female voices in positions of power there will be more equitable opportunities created for everyone.
