Habits and change: why change is hard and how small steps work

Simple versionRead the full chapter

Why it’s so hard to change, even when we really want to, and what actually helps: small steps, a kinder setup, patience with slips, and remembering that other people’s change belongs to them.

In short:

Why the tools work: this chapter explains the thinking behind these tools from earlier in the book.

Monday, 7:05am

The plan was a walk before work. The trainers are by the door. But the phone is in your hand, and somehow it’s 7:40 and you’re scrolling with cold coffee. By evening, a quiet voice says: “See? You never stick to anything.” That voice is wrong. You aren’t weak. You’ve met a habit.

  1. Change is hard for good reasons.

    Much of what we do each day runs on autopilot. That saves energy, which is why habits exist. The downside is that the old way is always quicker and easier than the new one. Change asks your brain to do something effortful, again and again, until the new way becomes the easy one.

    For example: Jodie wants to stop snapping at her kids in the morning rush. She means it every night. Every morning, the same rush brings the same snap. She isn’t a bad parent; the morning is a well-worn groove.

    Thoughts you could try: “This is hard because it’s a habit, not because I’m failing.” “Old grooves take time to fill in.”

    Try this: Pick one thing you’d like to change and write: “When does it usually happen? Where? What’s going on just before?”

  2. Habits run on cues.

    Most habits have a trigger: a time, a place, a feeling, a person, or the thing you just did. The cue starts the routine, and some kind of reward (relief, comfort, a little buzz) keeps it going. If you know the cue, you can plan for it.

    For example: A man notices he reaches for snacks not when he’s hungry but when he opens his laptop after dinner. The cue is the laptop. He starts making tea first instead.

    Thoughts you could try: “What happened right before I did that?” “What was I getting from it?”

    Try this: For three days, each time the habit happens, jot down the cue: time, place, feeling, or what you were doing.

    Dig deeper: cues and routines

    Figure 26 Habits run on cues. Over time the cue alone is enough, so change the setup, not just your willpower.
  3. Start smaller than feels useful.

    Big goals are inspiring but easy to drop. Tiny steps feel almost silly, and that’s why they work: they’re easy enough to do on a bad day. Tie the new step to something you already do: “After I put the kettle on, I’ll...” Once it sticks, you can grow it.

    For example: Two housemates want a tidier kitchen. Instead of a big weekly clean they never do, they agree: “After dinner, we each wipe one surface.” It takes two minutes, and the kitchen stays nicer.

    Words you could use: “Let’s start with something tiny, and see if it sticks.” “After I ..., I will ...”

    Try this: Shrink your change until it takes two minutes or less. Write it as “After I ___, I will ___.”

    Your done list

    Write down one small thing that went right, however small.

    This week: 4 small wins

    Went to the Thursday quiz with Rita and Joe · Thu, Oct 8 · With a friend

    Cleared one shelf in the spare room · Wed, Oct 7

    Rang my brother back · Tue, Oct 6 · With family

    Walked to the post office instead of driving · Mon, Oct 5

    A made-up example. Names and details are invented. A done list is for encouragement, not proving who does more.

  4. Change the setup, not just your willpower.

    Willpower runs low when we’re tired, hungry or stressed. Your surroundings don’t. Make the new habit easier (put it in sight, get things ready the night before) and the old one a little harder (move it out of reach, add a step). Small changes to your setup can do more than any amount of trying harder.

    For example: A teenager wants to sleep better. Instead of “trying not to scroll,” he charges his phone in the kitchen. It works far better than willpower ever did.

    Words you could use: (to yourself or a partner) “What could we change about the setup so this gets easier?”

    Try this: Make one small change to your space today that makes the new habit easier or the old one harder.

    Dig deeper: shaping your setup
  5. Being in two minds is normal.

    Part of you wants to change. Part of you doesn’t, and that part usually has its reasons: the old habit gives comfort, saves effort, or protects you from something. Pushing harder against that part rarely works. Listening to it often does.

    For example: Asif wants to drink less, but he also loves the Friday pub with his team. Instead of “never again,” he asks what Friday gives him: friends, laughing, unwinding. He keeps the Friday, and switches to alcohol-free after the first drink.

    Thoughts you could try: “What does the old habit give me?” “What would make the change worth it to me, not just to others?”

    Try this: Write two lists: “What I like about how things are” and “What I’d like about changing.” Both lists are allowed.

    Dig deeper: readiness and mixed feelings
  6. Slips are part of change.

    Nearly everyone who changes something slips back sometimes. One slip doesn’t undo your progress. What often does is the thought that follows: “I’ve blown it, so why bother?” Treating yourself kindly after a slip makes it more likely you’ll start again, not less.

    For example: After three calm weeks, a dad shouts at his son over homework. That night he says, “I shouted, and I’m sorry. I’m working on it.” The next day he’s back on track. The slip became a repair, not a reason to give up.

    Thoughts you could try: “A slip is a moment, not a verdict.” “What made today harder, and what can I plan for next time?”

    Try this: Decide now what you’ll do after a slip: one kind sentence to yourself, and one small step to start again.

    Dig deeper: slips and starting again
  7. Change sticks when it fits who you want to be.

    Change done only to please others, or out of shame, is hard to keep. Change that connects to what you care about, the kind of person, parent, friend or colleague you want to be, has deeper roots. Each small action is a vote for that person.

    For example: A woman who wants to “be better at keeping in touch” reframes it: “I’m someone who shows up for my friends.” Sending one voice note a week becomes part of who she is, not a chore.

    Thoughts you could try: “Who am I becoming with this step?” “This matters to me because...”

    Try this: Finish this sentence for your change: “I want to do this because I care about...”

    Dig deeper: values and who you’re becoming
  8. You can support change, but not force it.

    It’s natural to want people we love to change: to drink less, tidy more, look after themselves. But other people’s change belongs to them. Pressure tends to make people dig in. What helps more: saying clearly what you need, asking what would help, and noticing their small steps out loud.

    For example: A coworker keeps missing deadlines. Instead of “You need to be more organised,” his teammate asks, “What would make the handover easier for you?” They set up a shared checklist, and the deadlines improve.

    Words you could use: “I can’t change this for you, but I’d love to help if you want me to.” “I noticed you did that this week. That really helped.”

    Try this: Notice one small positive change someone else made this week, and tell them.

    Dig deeper: change with other people

Two weeks later, 7:05am

The trainers are still by the door, but the phone now charges in the kitchen overnight. The plan has shrunk too: shoes on and out to the end of the road. Some mornings that’s all. Most mornings it turns into a walk. On the day you miss, the voice says “See?” and you answer it: “A missed day is a slip, not a verdict. Tomorrow, the end of the road.”

In everyday life

On your own: a kind plan for change

If you’re working on something alone, put the ideas together in one small plan:

The individual program walks through this step by step: The self path and Know yourself, next.

Common mix-ups

Three rising curves that level off, reaching 95 percent of their own plateau at about 18, 66 and 254 days; a small dip shows a missed day is not a reset.

Words you could use: “I’m on your side with this. What would help?” “You’ve done this three days running. That’s not nothing.”
