The Student Observer: Why your teen brain is your secret weapon for building habits

“Your brain isn’t fully developed yet.”

I heard that again recently, after I forgot an assignment and procrastinated until 10 p.m. getting it done. Most conversations about the teen brain seem to focus on what’s still developing. What I’ve started to realize is that there may be some benefits to that too.

According to the National Institute of Mental Health, the brain continues developing throughout adolescence, especially the prefrontal cortex, the area involved in planning, decision-making, and self-control. Right now, your brain is like a city under construction. It’s changing and reorganizing itself in ways that help it become more efficient. You can think of neurons as buildings and the connections between them as roads.

Every time you practice something, whether it’s focusing during a long class, planning your week, or sticking to a routine, those roads get smoother. Eventually they become so well traveled that you don’t have to think about them as much anymore.

I see this in dance all the time. The first time I learn new choreography, it feels completely awkward. My brain is trying to get my body to do things it isn’t used to doing. But after enough repetition, something just shifts and my muscles know what to do without me having to think through every step. It doesn’t happen all at once, but it gets a little easier every time I practice.

The same thing happens with skills like time management or staying organized. Researchers at Harvard’s Center on the Developing Child explain that our brains have an ability to adapt and change based on our experiences—a process called neuroplasticity. Frequently used brain connections become stronger over time, while unused connections are gradually pruned away. In other words, roads that don’t get traffic eventually disappear.

When you open a planner, break a project into steps, or start studying before the night before a test, you’re strengthening the pathways that make those things easier next time. The same process can reinforce other patterns too. If we regularly rely on last-minute pressure or put off difficult tasks, those habits can become familiar as well.

None of us are going to do this perfectly. But learning more about how the brain develops has made me think more about the habits I’m building.

For me, balancing school, dance, and extracurriculars has made me appreciate the value of routines. They help me keep track of everything that’s going on and make busy weeks feel more manageable. Building those routines is something we can do at any age, but learning more about the teen brain has made me appreciate that these years are also a time of tremendous growth and change.

Maybe that’s one reason the teen years matter so much. We’re not just learning algebra, history, or choreography. We’re also learning how to manage ourselves.
