You have got to discover you, what you do, and trust it.

The line urges self-discovery as the foundation of authentic work: first identify who you are (“discover you”), then clarify the particular kind of work you do best (“what you do”), and finally commit to it with confidence (“trust it”). In Streisand’s case, the sentiment aligns with her public image as an artist who resisted being molded by industry expectations—valuing distinctive voice, taste, and instincts over conformity. More broadly, the quote frames creative and professional success as an inward process: competence grows from knowing one’s own sensibility and then having the courage to rely on it, especially amid external criticism or pressure to imitate others.
