Her best advice: "I proved myself to be very valuable,” Weiss told The Cut about being an intern first. “You have to be so many things. You have to be a sponge, you have to be respectful, you have to roll up your sleeves. I really earned my right to be there. I was just like, ‘Put me to work. I love work!’”
