Earn Your DOSE
What neuroscience, psychology and Stoicism agree about happiness
Your experience of life is not just what happens to you. It is what your nervous system does with what happens to you.
Happiness is not mystical. It is chemical. And those chemicals are influenced by behaviour.
Buckle up for this one….
Modern psychology often refers to a “DOSE” of wellbeing. You’ve heard of most of these words. Let’s focus today on finding a daily dose of each one….
Dopamine.
Oxytocin.
Serotonin.
Endorphins.
Four core neurochemicals that heavily influence motivation, bonding, mood and stress regulation.
What is remarkable is this. The most reliable ways to stimulate them are free.
Yup. You don’t need to blow 5 grand at a night club or drive a Maserati to get there. Every single one of us can achieve them all, regardless of our circumstances. I’ve seen the happiest people with the least “things” and the unhappiest with all the expensive toys you can imagine…
Let’s ground this properly.
Dopamine is the motivation and reward neurotransmitter. It is central to reinforcement learning. When you complete a task, make progress, or move towards a goal, dopamine pathways activate. This is not Instagram science. Researchers like Dr. Andrew Huberman have explained extensively how dopamine is tied not just to pleasure but to pursuit. It is about striving.
The problem in modern life is not dopamine deficiency.
It is dopamine dysregulation.
Endless scrolling, constant novelty and hyper stimulation create short spikes followed by crashes. Over time, this reduces baseline motivation. Think about that for a second and ask yourself how you can positively change that?
I’ll wait ….
Slow dopamine is different. It comes from effort.
Exercise.
Learning.
Finishing something hard.
Meditation.
Yes Like I said. All without financial cost but all come with rewards.
In short, your brain rewards you for effort aligned with meaning.
Oxytocin is the bonding hormone. It increases trust, connection and relational safety. Psychologist Sue Johnson, founder of Emotionally Focused Therapy, built an entire therapeutic model around attachment science. Her work shows that secure emotional bonds regulate stress and increase resilience.
Oxytocin is released through touch, eye contact, acts of kindness, shared vulnerability. Hug someone you love. Help a friend. Stroke a dog. These are not soft activities. They are neurobiological regulators.
You cannot biohack your way around loneliness.
Serotonin influences mood stability, confidence and overall wellbeing. Low serotonin has long been associated with depression and mood disorders. Sunlight exposure, regular movement and social belonging are well documented contributors to healthy serotonin levels.
Psychologist Martin Seligman, often called the father of positive psychology, emphasised that wellbeing is built through engagement, relationships and meaning, not passive consumption. His PERMA model aligns remarkably well with behaviours that naturally support serotonin balance.
Then there are endorphins. Your body’s natural painkillers. Released during physical exertion, laughter and even controlled discomfort. They reduce pain perception and increase resilience. The so called runner’s high is not myth. It is biology.
Notice the pattern.
Effort. Connection. Sunlight. Movement. Laughter. Presence.
None of these require wealth. They require willingness.
Now let’s bring the Stoics back in. My mate Seneca had done it again…
“It is not that we have a short time to live, but that we waste a lot of it.”
— Seneca
The Stoics did not have MRI machines. They did not know the word neurotransmitter. But they understood agency. They understood that while we cannot control events, we can influence how we train our mind and body to respond.
Modern psychology confirms what ancient philosophy suspected. Behaviour shapes emotion more reliably than emotion shapes behaviour.
You do not wait to feel motivated before acting. You act, and motivation follows.
You do not wait to feel connected before reaching out. You reach out, and connection grows.
You do not wait to feel confident before trying. You try, and confidence builds.
This is not toxic positivity. It is behavioural science.
Stop feeding only fast dopamine through your phone.
Stop avoiding discomfort that would build endorphin resilience.
Stop isolating when what your nervous system needs is oxytocin.
Stop hiding from sunlight and wondering why your mood dips.
Start earning your DOSE.
Go for a hard walk. Hug someone properly. Sit in the sun. Finish the task. Laugh until it hurts. Breathe deeply. Repeat.
Happiness is not a personality trait. It is a practice grounded in biology and strengthened by philosophy.
Or as Seneca might put it.
Your freedom is in how you choose to live today.

Stay Unshackled, My Friends,
