3 Smarter Ways to Stay Mentally Sharp
Three strategies for maintaining your cognitive edge and vitality.

This post is aimed at people who are no longer in early adulthood and are at least 10 years into their career or post-college.
As we reach our 40s and beyond, we often become concerned with maximizing our mental sharpness. Our concern can arise from aging, but also from managing a lot of demands (e.g., parenting and work, or bigger responsibilities at work), or factors like adapting to rapidly changing tech.
As we enter mid-career and beyond, we can start to feel less connected to identities related to our mental sharpness that we held earlier in our lives. For example, we may have seen ourselves as a fast learner, an early adopter, or a person who forges new or unconventional paths. Those identities can start to feel more distant as we enter different life stages, but we can regain that connection.
Here are three strategies for getting the most out of your brain (at any age or life stage).
1. Recognize When Recovery Has Become Your Bottleneck
As we age, how well we recover can become the main factor limiting our mental performance. Many effective strategies for staying sharp focus on improving recovery.
In sports, there is a saying: "You can only train as hard as you can recover."
When we're younger, the bottlenecks to what we can achieve are often motivation, knowledge, skills, or power/agency. As we age, the bottleneck often becomes recovery.
- You might feel motivated to work longer than you can concentrate.
- You might have more ideas than you can execute.
- You might want to do more exercise than you can recover from, especially higher-intensity exercise.
If recovery is your bottleneck, turn as many recovery dials as you can. We all have heard these before: sleep, nutrition, higher base physical fitness, and mindset. These will all affect your mental sharpness.
A lot of mental sharpness comes down to cellular energy. Many key strategies for mental sharpness focus on boosting physical energy and reducing mental energy drains like worry and rumination.
Although the main avenues are fundamental, there's plenty of creativity and personalization you can apply to your strategies. Solutions aren't scarce. Options to consider include filling nutrient gaps (use an app like Cronometer to see what you're missing), strength training to reduce daily activity drain, doing more exercise that's easier to recover from (e.g., Zone 2), naps, mind-body practices like yoga for mobility and mindset, and adding nutritional support (e.g., creatine).
If you feel frustrated with yourself and think the problem is motivation or discipline, you might have misdiagnosed the issue if your bottleneck is recovery.
During different life stages, your needs can change. For example, you might notice your chronobiology shifting (typically toward earlier bedtimes and rising). You might find you need more breaks on Mondays or Tuesdays to still be productive on Fridays. Or you might notice you need to manage electrolytes more carefully to optimize your energy levels.
2. Learn a Skill That Requires Formal Assessment
Once we're into our careers, we often reach a point where formal exams are no longer required. If it's been more than 10 years since your last formal test, consider setting a learning goal that requires one.
Why?
Learning tools change rapidly. By pursuing something you'll be evaluated on, you keep your ability to learn sharp. This boosts confidence. It feels good to know you can learn anything you want. Needing to pass a test also motivates you to explore all the current learning tools available.
Engaging in something tested can help you spot changes you might want to address, like if you've become uncomfortable with productive struggle (the process of grappling with problems to build understanding) or struggling with forms of learning that feel like drinking from a firehose (where too much information comes at once and is hard to absorb).
Consider setting a benchmark to maintain. For example, my benchmark is to feel capable of taking any undergraduate college-level class on any subject.
3. Adopt an Experimenter's Mindset to Grow
We feel better when we sense we're growing. That sense can come from exploring and experimenting. This also builds our resiliency and exposes us to more diverse positive emotions.
Research across fields (like computer science) shows optimal outcomes come from balancing exploration of new options with exploitation of proven ones. For example, you might visit the same restaurant you like four out of five Fridays, and try somewhere new the other time. Or you stick to a familiar routine most times you complete a task, but occasionally experiment with a new method.
As we age, the rewards from areas of life we've already explored deeply can start to level off. Some personal records (PRs) may be behind us. Since we can't break certain old records anymore, we need to find new avenues for growth. For instance, if you won't beat your mile PR from your 20s, you might try different race types where any new PR becomes your overall best.
In many domains that require practice to gain skills or make progress, a rough rule is that we experience about 10 years of obvious improvement, year after year, before progress slows and gains become harder to achieve.
All these ideas come together to show how we can grow from targeted experimentation and venturing beyond what we already know we like, domains we've achieved in, and what we know works.
Mental Sharpness Is Built on Self-Knowledge
These three strategies—optimizing recovery, pursuing evaluated learning, and maintaining an experimenter's mindset—provide different avenues for maintaining (and improving) your mental sharpness. A common thread is that they all require considerable self-knowledge, acquired through observation and reflection. These are not generic tips. Executing them requires you to learn a lot about yourself, like your specific nutritional gaps and how much exercise makes you feel energized vs worn out.
The fear of losing mental sharpness as you age, or when demands are taxing your recovery capacity, can be scary. Good strategies (like these) can help you thrive.
