"I think that one thing about learning to be the best friend you can possibly be is knowing when you have to let people figure things out on their own... and I do trust her," explained the "Out Of The Woods" songstress.
She continued, "I think she has good judgement, she's going to do amazing things with her life... she's incredibly intelligent. People — it would scare them if they knew how smart she is."
“[Taylor] just kind of looked at me and was like, ‘Selena, if you're the smartest person in the room, I think you're going to be in the wrong room,'" Gomez remembered. "She thinks I should constantly surround myself with people who are going to make me better, that are going to challenge and motive me. It kind of stuck to me. I want to surround myself with those people.”
But there is one thing Taylor won't do — tell Selena exactly what to do.
"Be there for your friends no matter what they're going through and never try to boss them around."
