Beyoncé: One is not born a leader, but becomes one

She is the epitome of a great leader. Beyoncé writes her own songs, lends her voice to her battles, and leads a career as a singer, actress and entrepreneur, without putting her personal life with Jay-Z on hold.

Her work focuses in particular on women's careers. Let us be enlightened by the halo of her knowledge.
