Demi Lovato has had her ups and downs, just like the rest of us, and now she’s sharing her advice on how to be confident, stay strong and always remain true to yourself.

Wearing bright red lipstick and rocking purple and blue hair, the 21-year-old singer covers Seventeen Magazine looking like the cool older sister everybody should have. She’s stepping in as guest editor at the mag so she can speak directly to girls about her personal struggles and how she consistently has the courage to face them. Check out what Demi shared:

On being confident: “I used to think that confidence came from what other people thought about me, and boys and everything else. But now I realize that confidence comes from what I feel about myself, and reassuring myself that I can do whatever I want and be whoever I want. Just knowing and setting up my future for a great life.”

On overcoming obstacles: “If things go wrong the first week of school it’s not the end of the world. I know it may seem like that, but it’s really not. There are going to be times where you will have bad days, bad weeks and even sometimes bad months — but rainbows always come after the darkest storm.”

On knowing things won’t always be easy: “Since I went to treatment, there have been days when it’s felt really easy, and I’ve felt great about where I am. But then I have moments when it’s not. That’s life. You can’t just take your mind and your body into the shop and get it fixed. It doesn’t come out repaired. It’s not like a car. It takes time — pace yourself. Every day is a new opportunity to change your life and be who you want to be.”

On giving back: “When I give back, I don’t question my self-worth. I know that if my career were to fall apart tomorrow — even if I were to never have money or fame again — I’d still have value in my soul, because I know that I can have an effect on someone else’s life.”

On standing up for yourself: “I’m impulsive when it comes to fighting back, but I’ve learned to reel it in. Tweeting without thinking does more harm than good. So take a second. Journal what you want to say, and then if you still feel the same later, that’s when you can tweet it.”
