11 Best Self-Help Books For Decision Making (For Women Who Are TIRED Of Overthinking)

Making decisions as an adult is genuinely exhausting.

Every choice suddenly feels like it carries the weight of your entire future.

Should you leave the relationship? Change careers? Move cities? Start the business? Stay where you are? Trust your gut? Be “logical”? Wait for clarity? Risk it? Play it safe?

And somehow, even deciding what to eat for dinner can turn into a full-blown identity crisis when you’re mentally overwhelmed enough.

If you’re someone who constantly:

• second-guesses yourself,

• overthinks every option,

• asks everyone else for advice before trusting yourself,

• or feels paralysed by fear of making the wrong decision,

I’ve got you!

Here is my official list of the best self-help books for decision-making that are actually worth reading.

1. The Mountain Is You: Brianna Wiest

This book genuinely feels like therapy for self-sabotage.

If your biggest problem with decision-making is that you:

• overthink yourself into paralysis,

• avoid change,

• fear failure,

• or constantly doubt yourself,

you need to read this.

Brianna Wiest explains how a lot of our indecision actually comes from emotional fear, not lack of capability.

A lot of us already know what we want to do.

We’re just terrified of:

• making the wrong choice,

• disappointing people,

• failing publicly,

• or becoming a different version of ourselves.

This book helps you recognise the emotional patterns keeping you stuck so you can start making decisions from self-trust instead of fear.

Perfect for:

• anxious overthinkers,

• people-pleasers,

• and women navigating major life changes.

2. The Psychology of Money: Morgan Housel

This might seem random for a decision-making list, but hear me out.

This book completely changes the way you think about long-term choices.

It’s technically about money, but it’s actually about:

• behaviour,

• emotional decision making,

• risk,

• habits,

• and human psychology.

One of the biggest reasons people struggle with decisions is because they’re constantly looking for the “perfect” option instead of the sustainable one.

This book teaches you how to think long-term instead of emotionally reacting in the moment.

Which honestly applies to:

• relationships,

• careers,

• wellness,

• confidence,

• and pretty much every life decision.

3. Untamed: Glennon Doyle

If you struggle to trust your own voice when making decisions, this book is SUCH an important read.

Especially for women.

Because a lot of us were raised to:

• prioritise being liked,

• avoid disappointing people,

• seek validation,

• and ignore our instincts.

Untamed is basically about unlearning all of that.

It encourages you to stop outsourcing your decisions to:

• society,

• family expectations,

• relationships,

• or what looks “acceptable” online.

And instead start asking: “What do I actually want?”

Simple question. Weirdly difficult answer sometimes.

This book feels empowering without being fake motivational fluff.

4. Essentialism: Greg McKeown

If you’re overwhelmed because you’re trying to do EVERYTHING at once, this book will genuinely calm your nervous system down.

The core idea is simple: not everything deserves your energy.

A lot of decision fatigue comes from constantly saying yes to things that don’t actually matter to us.

This book helps you:

• prioritise better,

• simplify decisions,

• stop overcommitting,

• and focus on what actually moves your life forward.

Honestly one of the most practical self-help books for decision making if your brain constantly feels overstimulated.

5. The Gifts of Imperfection: Brené Brown

A lot of indecision is rooted in perfectionism.

You’re scared to make the “wrong” choice because you think one bad decision means you’ve failed completely.

This book helps you let go of that mindset.

Brené Brown talks a lot about:

• shame,

• vulnerability,

• perfectionism,

• and self-worth.

And honestly? Those things affect decision making WAY more than people realise.

Because confident decision makers aren’t people who never fail.

They’re people who trust themselves enough to handle the outcome either way.

6. Atomic Habits: James Clear

This book is incredible if you constantly feel overwhelmed trying to “change your life overnight.”

One of the best lessons in this book is that small decisions repeated consistently matter more than dramatic life transformations.

Which is honestly reassuring.

Because sometimes the best decision isn’t:

• quitting your job tomorrow,

• moving across the world,

• or reinventing yourself completely.

Sometimes it’s:

• waking up earlier,

• setting better boundaries,

• moving your body more,

• or being slightly kinder to yourself daily.

Tiny shifts compound.

This book explains that brilliantly.

7. Don’t Believe Everything You Think: Joseph Nguyen

If your thoughts constantly spiral into worst-case scenarios, read this immediately.

This book focuses heavily on:

• anxiety,

• overthinking,

• mental suffering,

• and thought patterns.

One of the most powerful takeaways is realising that not every thought deserves your trust.

Which sounds obvious until your brain convinces you that replying “okay” instead of “okay xx” means someone hates you.

It’s short, easy to read, and incredibly calming.

Perfect for anxious decision makers.

8. Big Magic: Elizabeth Gilbert

This one is especially good if your decisions are connected to creativity, career changes, or starting something new.

A lot of women stay stuck because they’re waiting to feel fearless before taking action.

This book teaches you that fear doesn’t disappear first.

You just stop letting it make every decision for you.

It’s inspiring without being aggressively “hustle culture,” which I appreciate deeply.

9. Set Boundaries, Find Peace: Nedra Glover Tawwab

Honestly? Half of our bad decisions come from weak boundaries.

This book explains:

• people-pleasing,

• emotional exhaustion,

• resentment,

• and boundary-setting

in such a practical, easy-to-understand way.

If your decision making gets heavily influenced by guilt or fear of upsetting people, this book will help massively.

10. 101 Essays That Will Change The Way You Think: Brianna Wiest

This is one of those books you underline constantly.

The essays are short, easy to read, and packed with mindset shifts around:

• self-awareness,

• emotional intelligence,

• fear,

• healing,

• and personal growth.

It’s particularly good if you’re in a “what am I doing with my life?” phase right now.

Which honestly feels like most of us at some point.

11. Attached: Amir Levine & Rachel Heller

If your decision making becomes chaotic in relationships specifically, this book is genuinely eye-opening.

It explains attachment styles and why some people:

• overanalyse relationships,

• struggle to leave unhealthy situations,

• fear abandonment,

• or constantly seek reassurance.

Once you understand your attachment patterns, relationship decisions suddenly become MUCH clearer.

And honestly? That self-awareness changes everything.

The truth is, no self-help book can magically make your decisions for you.

But the right books can help you:

• trust yourself more,

• quiet the noise,

• stop spiralling,

• and make choices from clarity instead of fear.

Because confident decision making isn’t about always knowing the “right” answer.

It’s about believing that you can handle whatever happens next.

And honestly? That mindset changes your entire life.
