5 Of The Biggest Mistakes People Make On Their Way To Lasting Change.

Many people start the journey toward personal change with genuine motivation. Whether the goal is improving health, developing new habits, managing stress better, or creating more balance in life, the desire for change is often strong at the beginning.

Yet lasting change can feel frustratingly difficult.

This isn’t because people lack willpower or discipline. In fact, research from positive psychology, behavioural science, and lifestyle medicine shows that sustainable change is possible—but it tends to happen under the right conditions.

Often, the biggest barriers are a few common mistakes that quietly undermine progress.

Here are five costly mistakes that can sabotage your path to lasting change—and what science suggests works better.

1. Relying on Motivation Instead of Systems

Motivation is a powerful starting point, but it is also unreliable. Energy and enthusiasm naturally fluctuate depending on sleep, stress levels, workload, and life circumstances.

When change depends solely on feeling motivated, progress often stalls.

Behavioural science consistently shows that systems and structures matter more than bursts of motivation. Small environmental changes can make positive behaviours easier and more automatic.

For example:

• Preparing healthy meals in advance makes nutritious eating easier.

• Scheduling exercise in the calendar increases follow-through.

• Setting reminders or cues helps reinforce new habits.

Lifestyle medicine emphasises the same principle: sustainable health behaviours emerge when the environment supports the behaviour.

The key question becomes: What systems can make this change easier to repeat consistently?

2. Trying to Change Too Much at Once

A common mistake when people feel inspired to change is attempting to transform multiple areas of life at the same time.

For example, someone might decide to:

• exercise daily

• completely overhaul their diet

• wake up earlier

• start meditation

• reduce screen time

While the intention is admirable, the brain tends to resist large-scale change all at once.

Research on habit formation shows that smaller, manageable changes are far more sustainable. Repeated small actions allow the brain to gradually build new neural pathways.

Positive psychology often refers to this as the power of small wins. Each successful step builds confidence, reinforces identity, and increases the likelihood of continuing.

Instead of trying to change everything at once, it is often more effective to ask:

What is the smallest meaningful step I can take today?

3. Ignoring the Role of Energy and Wellbeing

Many people try to change their behaviour while running on low energy, high stress, and poor sleep.

Unfortunately, this makes change much harder.

Lifestyle medicine research highlights that foundational health behaviours—such as sleep, nutrition, movement, and stress management—directly influence cognitive performance, emotional regulation, and decision-making.

When energy is depleted, the brain naturally defaults to familiar habits, even when those habits are not aligned with long-term goals.

Supporting wellbeing creates the biological conditions that make behaviour change easier.

This might involve:

• prioritising sleep routines

• taking short movement breaks during the day

• building moments of recovery and reflection

• reducing chronic stress where possible

Change becomes more sustainable when your physiology supports your intentions.

4. Expecting Immediate Results

One of the most discouraging aspects of behaviour change is that meaningful results often take longer than expected.

The brain and body adapt gradually. Whether the goal is improved fitness, reduced stress, or better habits, progress tends to occur incrementally rather than dramatically.

Positive psychology research emphasises the importance of focusing on progress rather than perfection. Recognising small improvements helps sustain motivation and reinforces new behaviours.

Instead of asking:

“Why haven’t I changed yet?”

It can be more helpful to ask:

“What small progress have I made this week?”

Celebrating small gains helps the brain associate change with positive emotions, which strengthens long-term commitment.

5. Trying to Change Alone

Human behaviour is strongly influenced by social environments. Supportive relationships can significantly increase the likelihood of sustaining change.

Research in both positive psychology and lifestyle medicine highlights the importance of social connection and accountability when forming new habits.

People are more likely to sustain change when they:

• share goals with others

• work with a coach or mentor

• participate in group programmes

• build supportive communities around shared goals

Encouragement, feedback, and shared experience can make the process of change feel less isolating and more achievable.

Lasting change is rarely a solo journey.

Building Change That Lasts

The good news is that lasting change does not require perfect discipline or constant motivation.

Instead, evidence suggests that sustainable change becomes far more achievable when we:

• build supportive systems and environments

• start with small, manageable actions

• prioritise energy and wellbeing

• recognise incremental progress

• seek support and accountability

When these conditions are in place, change stops feeling like a constant struggle and begins to feel like a gradual, natural process.

And over time, those small shifts can lead to meaningful and lasting transformation.
