As the overused saying goes, hindsight is 20/20. And knowing everything that we do now, there are a lot of things we would have done differently if we could give some sage advice to our younger selves—namely, don't tweeze your own eyebrows. Of course, Jennifer Aniston's words of wisdom completely trumped ours. During a recent chat with the star, we just had to ask, what sort of advice would you give your 20 year-old self? "First, of course, would be to wear sunscreen! That's a big one," she tells us. "And don't sweat it. It's all gonna be good. It all seems so serious and daunting, there's the pressure that everything has to be perfect, and you wanna grow up. Just relax and enjoy your youth."

Aniston's warmth and confidence radiates on-screen and at every red carpet event she attends, though a little self-love went a long way in reaching that point. "Developing your inner beauty is so important. Truthfully, beauty is in the eye of the beholder and there are so many versions of what that is. It's really about loving yourself, being good to yourself, and being healthy," she continues. "It's important to think about what you put inside your body, but also what you put inside your ears and what you put inside your mouth. All of that is very precious."
