How does a student’s mental state influence their ability to learn and retain information?
There are many studies showing that our mood affects our performance. Positive moods tend to broaden our perspectives — when we feel good, we’re able to process more possibilities, which can boost our innovation and creativity.
How can students redefine their idea of success to prioritize both achievement and happiness?
There’s a lot of evidence that shows that focusing on your happiness in your college years is correlated with the metrics of achievement and success students are usually striving for. One study by Diener and colleagues found that a student’s cheerfulness at age 18 even predicts their salary and job satisfaction more than 15 years later. I think students need to recognize that our happiness matters for future success more than we expect.
If a student feels stuck in a negative mindset about school, what’s one small change they can make today to start shifting that?
I think the most important change is for students to recognize that they have some agency over their mindset. There are things they can do to think differently about school and any other situation.
If you could design a mental health toolkit for students heading to college, what would be in it?
I’d give students a toolkit with strategies they can use to develop healthier behaviors and mindsets. Behaviors students can use to boost happiness include:
- Prioritize Social Connection: One of the biggest mistakes students make is prioritizing grades and productivity over friendships. However, the research is clear: Meaningful relationships are the No. 1 predictor of happiness. So, say yes to that coffee invite, join a club, or just make small talk with a classmate — it all adds up. Even tiny interactions, like chatting with a barista, can boost your mood.
- Embrace Time Affluence: Time affluence is the subjective sense that we have some free time. Most students today are time-famished, rushing from one task to the next. However, studies show that people who feel like they have more time are actually happier. Students need to protect their time affluence. Some strategies: Be intentional about how you spend your free moments. Instead of mindlessly scrolling on your phone, do something that genuinely recharges you — go for a walk, call a friend, or just breathe.
- Get Moving: Studies show that exercise isn’t just good for your body — it’s huge for mental health. Research shows that cardio exercise can reduce rates of depression and anxiety. You don’t need to be a gym rat to see benefits — dancing in your dorm room, stretching, or biking to class all count.
- Prioritize Sleep: Many parts of student life make it easy to skimp on sleep. However, sleep is one of the most important tools in our mental health kit. Aim for 7-9 hours a night, and make sure you’re practicing good sleep hygiene by keeping your phone as far away from your bed as possible (otherwise, the temptation to grab it in the middle of the night is far too high).
There are also mindset shifts students can use to feel happier. A few important ones to keep in mind are:
- Self-Compassion: One of the biggest traps students fall into is being their own worst critic. You bomb a test, miss a deadline, or say something awkward in class, and suddenly, your brain is in full-on self-attack mode. However, research shows that this kind of self-criticism doesn’t make us perform better — it just makes us feel worse. Research has found that people who practice self-compassion (treating themselves with kindness rather than judgment) are more resilient, more motivated, and less anxious than those who constantly beat themselves up.
- A Mindset of Gratitude: Our brains are wired to focus on what’s wrong. However, studies show that you can train your brain to notice more of what’s good. Studies also show that people who regularly practice gratitude have higher levels of happiness, lower stress, and even better sleep. So, scribble a few things in your gratitude journal, or commit to expressing your thanks to the people around you.
- Become More Present: College life can feel overwhelming. There’s always another assignment, another social event, or another thing to do. Your brain is constantly jumping between the past (“I should have studied more”) and the future (“What if I fail?”). However, research shows we feel best when we’re fully present in the moment. Research by Matt Killingsworth and Dan Gilbert found that people’s happiness levels drop when their minds wander — even if they’re thinking about something pleasant. Get out of your head and find ways to find the joy of the present moment.
What’s one piece of advice you wish every college student knew about happiness and well-being before stepping on campus?
Our happiness is much more under our control than we think. With simple changes to our behaviors and mindsets, we can all feel better.
How can students balance academic pressures with self-care without feeling guilty about taking breaks?
My biggest piece of advice would be that students need to remember that self-care isn’t a distraction from success — it’s actually a tool for success. A lot of students feel guilty about taking breaks because they think rest is “unproductive.” However, research tells us the opposite: When you prioritize well-being and get the rest/sleep/care you need, you actually perform better academically.
One strategy I share with my students is to reframe breaks as a performance strategy. Instead of thinking, “I don’t deserve a break until I’ve done enough work,” flip the script and think, “Taking a break will help my mind recharge so I can do better work.” When you take a break, remind yourself: “This is not wasted time — this is me investing in my brain’s ability to learn.”
I think this is also another spot for Kristin Neff’s strategy of self-compassion. If you’re feeling guilty about taking a break, remember that you’re only human, and all humans need breaks and rest. The next time you feel guilty for resting, literally repeat these phrases in your head: “Taking care of myself is part of being a great student,” or “I will be kinder to myself so I can show up as my best self.”
Many students feel overwhelmed when choosing a college or major. What advice would you give them about making big life decisions?
A lot of students stress about picking the single right college or major that will lead to a meaningful and happy career. However, the science of happiness tells us that this kind of fulfillment isn’t just about what you do or what college you end up in — it’s about how you shape your work to align with your strengths and values. This is where job crafting comes in.
Job crafting is the idea that you can reshape how you spend your time (including at work or in your major) to make it more fulfilling. Research on job crafting by Amy Wrzesniewski shows that fulfillment isn’t just about what you do, but how you approach it. You can craft your major by focusing on courses and projects that align with your strengths, connecting with mentors and peers who inspire you, and reframing tasks to see their deeper purpose.
