Selena Gomez's advice from Taylor Swift
"I was talking about relationships in business and in my life and she just kind of looked at me, and she supports me, never judges me, and she's like, 'Selena if you're the smartest person in the room then I think you're gonna be in the wrong room.' Because she just thinks I should constantly surround myself, and I agree with her, with people that are going to challenge me, motivate me, and it stuck with me. So I just kind of mentally repeat that to myself now."
