Why do so many New Year's resolutions fail?


The short answer is that lasting behaviour change is difficult. Most resolutions fail because our brains naturally return to familiar habits, especially when we're tired, stressed or busy. The good news is that habits can be changed with the right strategies and consistent practice.


Have you heard the word defenestration?


It means throwing something out of a window.


Unfortunately, many New Year's resolutions seem to suffer exactly that fate. By February, healthy eating, exercising more or saving money have often been thrown out the window.


If this sounds familiar, you're certainly not alone.


The problem usually isn't a lack of willpower. More often, it's because our brains prefer familiar routines over new behaviours.


Why is it so hard to change habits?


Our brains are designed to conserve energy.


Once a habit has been repeated many times, it becomes automatic. That is why it's often much easier to return to old behaviours than continue with new ones.


For example, it can feel easier to:

  • Eat another piece of chocolate when you're trying to improve your diet.

  • Use your credit card when you're trying to save money.

  • Pour another glass of wine when you've decided to cut back.

  • Delay studying when your goal is to gain a qualification.

  • Skip exercise when you're working towards better fitness.

  • Avoid decluttering when you've promised yourself you'll organise the house.


Sound familiar?


You're not alone. Almost everyone experiences setbacks while trying to create new habits.


Is self-sabotage holding you back?


Sometimes we know exactly what we should do, yet we still make choices that move us away from our goals.


You might hear an inner voice saying:

"Just this once won't matter."

or

"I'll start again tomorrow."

Other times we convince ourselves that:

  • We don't have enough time.

  • The timing isn't right.

  • Something else is more important.

  • We'll feel more motivated later.


These thoughts often become patterns that make lasting change much harder.


Rather than blaming yourself, it can be helpful to ask:


What is really stopping me?


Sometimes there is an underlying emotional trigger, habit or belief that needs to be addressed before lasting change becomes easier.


How can Brain Coaching help?

Brain Coaching aims to help people understand what may be contributing to unhelpful habits and develop practical strategies for lasting behaviour change.


The process generally involves three steps.


1. Identify the underlying trigger

Sometimes the reason behind a habit is obvious.


Sometimes it isn't.


Brain Coaching explores the thoughts, emotions or experiences that may be keeping unwanted behaviours in place.


2. Work through the underlying issue

Once the trigger has been identified, the next step is helping reduce its emotional impact so it no longer drives automatic behaviours.


3. Build new habits

The final step is creating practical strategies that fit your lifestyle.


The goal is not perfection.


The goal is developing new habits that become easier with repetition.


Five ways to make your goals stick

1. Start small

Large goals often feel overwhelming.


Break them into smaller, manageable actions that you can achieve consistently.


2. Expect setbacks

Missing one workout or eating one unhealthy meal does not mean you've failed.


Progress is built over time, not through perfection.


3. Celebrate small wins

Every completed step reinforces confidence and motivation.


Recognise your progress, no matter how small.


4. Focus on today's action

Instead of thinking about the entire journey, ask yourself:


What is one thing I can do today?


Small actions repeated consistently create lasting change.


5. Keep going

Television presenter Todd Sampson has encouraged people to "hang in there five more minutes."


Whether you're working towards better health, studying, building a business or improving relationships, perseverance often makes the difference.


Sometimes all you need to do is stay with the challenge a little longer.


Progress builds confidence


Every goal you achieve becomes evidence that you are capable of achieving the next one.


As Thomas Edison famously said:

"If we did all the things we are capable of, we would literally astound ourselves."

Small successes build confidence.


Confidence builds momentum.


Momentum creates lasting change.


Frequently asked questions


Why do New Year's resolutions fail?

Many resolutions fail because people try to change too much at once or rely on motivation alone. Long-term behaviour change usually requires consistent habits and realistic goals.


How long does it take to build a new habit?

There is no single timeframe. Research suggests habit formation varies depending on the person and the behaviour. Consistency is generally more important than speed.


What is self-sabotage?

Self-sabotage refers to behaviours that interfere with achieving your own goals. It often happens automatically and may be linked to stress, fear, low confidence or established habits.


Can Brain Coaching help with habits and motivation?

Brain Coaching aims to help identify unhelpful thinking patterns, develop practical strategies and reinforce healthier habits that support long-term goals.
