As your kids get older, do you ever think about high school and make mental lists of advice you want to give them? What you loved? What you would have changed? What you didn’t understand yet as a teen, but wish you had? I’m working with OLLY on a 2-part series about advice we would give our former teenage self, and our current teenage daughters.

OLLY offers a unique collection of vitamins, supplements and protein powders that don’t require a PhD in Chemistry to understand. Are you familiar with their line? I was originally introduced to OLLY a couple of years ago when they first made their debut at Target. Every OLLY product is packed with super effective, complex nutrients in a simple, expertly blended dose of just what your body needs to thrive. Plus — and this is a big plus — they’re really yummy! They make taking your vitamins a delight. And the entire line is so easy to use that you can mix and match to your heart’s content.

Recently they launched OLLY Girl, a multivitamin that’s made for girls age 12-17. It’s the perfect go-to product during those crucial growing years. OLLY Girl is packed with 15 essential vitamins and minerals to support strong bodies and bones, and a healthy immune system — including brilliant B vitamins to boost energy. It’s formulated with biotin to help with hair and nail growth, and it works from inside to support clear, healthy skin. It’s like a little chewy bite of perfection made just for your daughter. If she’s an unstoppable force (and she is!), then this is nutrition that keeps up.

Speaking of unstoppable forces, that’s exactly how I think of our 3rd child, Olive. Olive is our current high-schooler. She’s a sophomore and she’s thriving. She eagerly follows current events and is passionate about supporting projects that advance women’s rights around the world.Her AP Human Geography teacher, Ms. D, gave her a book about social justice, called What We Do Now, with a hand-written note that said: “Your passion for social justice and world exploration is incredible. I want to be like you when I grow up. For real, stay woke and keep fighting for what’s right.”

She’s also incredibly creative. She’s writing a play with her theater department and will be workshopping it next month, and performing it this spring. She plays piano and guitar. She goes to every indie band concert she can get all-ages tickets to. She takes hard classes and gets good grades. She’s an in demand babysitter and she works 15 hours a week at a part-time job. She has a fantastic sense of style and fashion.

Her latest project? She’s working with a group of friends to launch a teen-focused magazine called Dysfunction. They put out a call for submissions, they’ve been learning how to do layouts digitally and on paper. They’ve been talking to printers both in town and online. It’s a super cool project and I’m excited to see it come to life.

My advice to my teen self? My advice to Olive? Do something or create something in your teen years that you can touch and see and that makes a mark on the world. Start a band and get a gig. Record the album. Take the photography class and do fashion photo shoots that you share online. Write and submit the article. Make a movie. Publish a magazine.

It doesn’t have to be a huge production, but no matter the scope, it’s super valuable. Because projects like that are a chance to get genuine, real-world feedback. As a teen, it’s easy to get caught up in the world of high school, and forget that the rules are different in school than they are in real life. When a teen takes on a project that challenges them to use their best effort, but isn’t measured by a grade or the approval of an adult, they experience huge opportunities for growth and development.

I mean, I like high school sports, but not as much as a group of high schoolers who start a band. Because in high school sports, the students are to some degree following the plans and ideas of an adult. With their own band, they decide when and how to rehearse. They arrange the gig. They post the fliers. 

As an extra bonus, projects like that also create something real and tangible to look back on. Something to show your kids some day. Solid proof that you took on a challenge, learned a skill, made something happen. They’re a reminder to yourself that you’re capable of doing it again.

Olive is right on track. And I’m glad we have access to things like OLLY Girl that help her stay strong and healthy so she can shine her brightest and tap in to her innermost strength when she needs to. Would you like to try OLLY Girl? Find it here.

What’s your take? Did you get the chance to make a mark as a teenager? Did you write a song or record an album? Did you make good art — not as an assignment, but because you wanted to? Did you write a book? Publish an article? Make a movie? Write a script? Build something that’s still around? If yes, are you still proud of yourself when you think of it? I’d love to hear.

I’m also curious: What the biggest piece of advice would you give your teenage self (or your own teenage daughter)?
