Why Your Bad Habits Aren't a Willpower Problem - They're a Chemistry Problem

If you've ever tried to break a bad habit, you'll know exactly how much power habits have over us, day in and day out. Whether you realise it or not, your life is built almost entirely out of habits - good and bad. Getting up in the morning, brushing your teeth, checking your emails, driving to work: our brains are remarkably efficient at automating these actions so we no longer have to think about them consciously. That's exactly why they're so hard to break.

If the pandemic left you with a habit or two you're not proud of - one too many trips to the fridge, one too many hours lost to Netflix - you're in good company. The good news is that habits aren't fixed. They can be examined, redesigned, and rebuilt, and two books make an especially compelling case for how.

The case for small changes: Atomic Habits

James Clear's Atomic Habits has sold over 3 million copies worldwide and topped the New York Times bestseller list, and it's easy to see why. The book lays out clear, practical "do's and don'ts" for building helpful habits and dismantling unhelpful ones. Its central message is refreshingly simple: lasting change doesn't come from dramatic overhauls; it comes from small, consistent actions repeated daily. As Clear puts it:

"If you were able to improve by 1% each day for an entire year and those gains compound, you would end up 37 times better at the end of the year."

That's the whole philosophy in one sentence. Tiny habits, repeated consistently, compound into outsized results - and the reverse is just as true for bad habits left unchecked.

The case for brain chemistry: The DOSE Effect

Where Atomic Habits explains the mechanics of habit formation, neuroscientist TJ Power's The DOSE Effect explains why those small daily actions actually make us feel better. Power's framework centres on four brain chemicals that drive our motivation, mood, and resilience: Dopamine, Oxytocin, Serotonin, and Endorphins (DOSE, for short). Each governs something different - dopamine fuels drive and focus, oxytocin builds connection, serotonin lifts mood and energy, and endorphins relieve stress.

Modern life, Power argues, quietly throws all four out of balance: constant scrolling, poor sleep, isolation, and sedentary routines slowly erode our baseline wellbeing. His research is striking - having trained over 50,000 people using the DOSE method, he recorded improvements of 48–

59% in concentration, motivation, energy, and sleep quality. The takeaway lines up neatly with Clear's: small, deliberate daily habits aren't just productivity hacks; they're a direct lever on your brain chemistry and, ultimately, your happiness.

Put the two books together, and the message is hard to argue with: tiny habits compound into big results (Atomic Habits), and those same tiny habits are also quietly rebalancing your brain chemistry for the better (The DOSE Effect). It's a case for good habits made from both the outside in and the inside out.

Six habits worth adopting

Here are six manageable habits you can weave into your day that draw on both of these ideas - some rooted in behavioural design, others in resetting your brain chemistry.

1. Prepare your day the night before. Preparing the night before means you go to bed knowing tomorrow is already organised - and wake up calmer for it. In the evening, check what meetings you have, gather what you need, sort your lunch, and pack your bag. It's a small act of dopamine management too: starting the day without decision fatigue means less scrambling and more focus.

2. Write down your thoughts. A cluttered mind is a stressed mind. If you have things to prepare for or remember, get them out of your head and onto paper. Studies show this simple act reduces anxiety and increases our sense of control. It's especially effective before bed - decluttering your mind helps you relax and sleep better, which in turn supports the serotonin and energy levels Power links to a well-regulated brain.

3. Delay your responses. When emails and calls land, we're often too quick to respond and get them dealt with - which can mean rash decisions and overcommitment. There's nothing wrong with buying yourself thinking time: "I'll look into that" or "let me check my calendar and come back to you" are both perfectly reasonable. As long as your initial reply is timely, this gives you space to check your workload and reassess your priorities, sparing you the stress of overcommitting or double-booking.

4. Put the phone away. The constant ping of notifications is relentless. On average, it takes 23 minutes to refocus after checking your phone. Power's research on dopamine is directly relevant here: constant scrolling gives us small, cheap hits of dopamine that leave us less motivated for everything else, not more. Try setting yourself a specific window to check your phone, then lock it away for the rest of your working stretch - your focus (and your brain chemistry) will thank you.

5. Review the day. Take five minutes at the end of your working day to reflect. Note what you accomplished and what you didn't. Focus on the positives, but also consider whether doing something differently might have changed the outcome. This is habit tracking in its simplest form - exactly the kind of feedback loop Clear argues is essential for habits to stick.

6. Read more. Curiosity and self-development go hand in hand with success - from Bill Gates to Oprah Winfrey, most great thinkers are committed readers. Just 15 minutes a day can meaningfully expand your knowledge and skills over time. If books aren't your thing, try podcasts or audiobooks during your commute or workout. This is how I get through a book a month; I just listen whenever I am in the car.

Time to take action

Try weaving some of these habits into your daily routine and notice the difference they make. As both Clear and Power make clear in their own ways - one through the maths of compounding, the other through the chemistry of the brain - small, consistent changes are never as small as they seem. It's time to take action: break the bad habits and build some better ones.
