100 Ways to Change Your Life: The Science of Leveling Up Health, Happiness, Relationships and Success

Honestly, I’ve been following Liz’s podcast for years and this book is like having her best episodes in my pocket. Every tip is backed by science, which makes me feel way more confident about actually trying them. I love that it’s not just one long narrative you have to trudge through. You can just flip to whatever you need help with—like sleep or anxiety—and find something actionable right away. It’s beautifully designed too. Personally, I found the section on morning routines particularly game-changing because it didn't require me to buy a $1000 supplement or anything crazy. It’s just solid advice for real people who want to feel better without a total overhaul.

This is a great reference book. I love that I can skip around chapters depending on what I’m feeling that day. The presentation is gorgeous and the tips are actually doable. It’s not just fluff; there’s real science behind what she’s saying, which I really appreciate. I’ve already started using the habit-stacking tips and they’re actually working for my morning routine. Honestly, I think it’s a perfect gift for anyone who feels a bit stuck but doesn’t want to read a 400-page manifesto on wellness. It's concise and visually appealing too! Definitely one I’ll keep on my nightstand for a long time.

If you like science-backed advice, this is your holy grail. I’ve read a lot of self-help, and usually, it's just vibes and anecdotes. Moody actually brings the experts in. Every single tip feels grounded in real data, which makes me much more likely to actually try the suggestions. I really enjoyed how the book is structured—you don't have to read it cover-to-cover, which is a relief. I just pick a topic I'm struggling with, like energy levels or gut health, and find three things I can do today. It’s a stunning book physically, too. It feels like a high-quality manual for being a human. Highly recommend for the skeptics out there!

I honestly didn't expect to love this as much as I did. I’ve been feeling really stuck lately, and the way Liz breaks things down made everything feel less overwhelming. It’s not about changing your whole life overnight; it’s about these tiny, science-supported shifts that actually add up. I felt like she was talking directly to me in the chapter about overcoming fear. It’s such a beautiful book to look at, and I keep it on my nightstand to flip through whenever I need a little boost. It’s probably the most 'useful' book I’ve bought in years. It’s helped me regain a sense of agency over my daily habits and mental state.

I'll give it a four because the layout is fantastic, but if you’re a self-help junkie, some of this might feel like a repeat of things you've heard before. I felt like the advice was very grounded in expert research, which I appreciate, but it does occasionally lean into that 'hustle' culture vibe that gets a bit exhausting. That being said, it’s probably the most practical book on my shelf right now. The chapters are short—perfect for when I only have five minutes between meetings. It might not be for everyone, especially if you want a deep dive into one specific psychological issue, but as a general 'how-to' for life? It's pretty solid.

As a working mom with a toddler, I don't have time for long-winded philosophy. Liz Moody gets that. This book is divided into 100 bite-sized pieces, making it incredibly easy to digest while I'm drinking my coffee before the house wakes up. Some of the suggestions felt a bit out of reach financially—hiring help isn't exactly in my budget—but I could easily skip those and find ten other things that were free and easy to implement. It’s a very practical, actionable resource. I personally loved the section on building better relationships; the advice felt fresh and wasn't just the usual 'communication is key' stuff we've all heard a million times before.

I’m giving this four stars because it’s incredibly practical, but with a small caveat. Some of the tips feel like 'hacks' rather than real solutions. For instance, some of the advice on productivity feels very tied to a capitalist mindset of always doing more, which I’m trying to move away from. However, the sheer volume of ideas means there is something for everyone. I found the journaling prompts surprisingly helpful, even though I usually hate journaling. It’s written in a very accessible way, and Liz's voice is friendly without being too 'guru-ish.' It’s a great starting point for someone looking to optimize their life without getting bogged down in theory.

This book is definitely not your typical self-help read. Instead of one long argument, it’s a massive compilation of actionable ideas. I’ve seen some people complain about the privilege in some of her tips—like the outsourcing cleaning thing—and yeah, I see that. It’s a valid criticism. But if you can look past those few points, the rest of the book is gold. Most of the tips are totally free or very low-cost. I loved the section on 'social health,' which is something I’ve never seen addressed so clearly before. It’s easy to understand and even easier to implement. A solid 4 stars for the sheer amount of work that went into this.

I have mixed feelings. On one hand, the tips are fetchingly useful and very well-researched. On the other hand, it felt a little like a giant advertisement for her podcast. Almost every section ends with a 'listen to episode X for more,' which got a bit repetitive after a while. If you aren’t already a listener, you might feel like you’re missing half the story. I also think some of the 'hacks' are a bit surface-level—like, a cold shower isn't going to fix deep-seated burnout. It’s a nice compilation, but it lacks the depth I was looking for in a life-changing guide. Good for a coffee table, maybe not for a soul-searching journey.

I really wanted to like this, but I struggled with the tone. There's a section where she suggests 'outsourcing' things like cleaning to save time, and honestly, it felt so tone-deaf. It’s written from a place of extreme privilege that just doesn’t resonate when you’re barely making rent. She talks about hiring people to prep healthy meals like it’s a tip anyone can just pick up. While the science bits are interesting, the capitalist undercurrent made it hard for me to finish. If you have the disposable income to hire a chef, you’ll love it, but for the rest of us, it feels a bit like a slap in the face. It just wasn't for me.
