Buy This, Not That: How to Spend Your Way to Wealth and Freedom

Finally got around to reading Sam Dogen’s debut and it’s easily the most comprehensive coverage of the stock and housing markets I’ve seen in years. Most FIRE books just tell you to eat lentils and buy VTSAX, but this actually goes into the math of life. I specifically loved the 30/30/3 rule for home buying. It’s conservative, sure, but in this economy, you need a buffer. The writing is incredibly clear and easy to understand even when he’s diving into complex probability matrices. The 70/30 philosophy for decision-making has already changed how I approach my career moves. I’ve been a follower of the Financial Samurai blog for a long time, and this book feels like the ultimate distillation of his best wisdom. Truly an excellent investment that will likely generate 100x more value than the cover price.

Real estate advice in most personal finance books is usually just a footnote, but Dogen actually dives into the mechanics of property as a wealth builder. The 30/30/3 rule is a game changer for anyone trying to figure out if they can actually afford a mortgage in a high-cost area. I also loved the 70/30 philosophy. We often get paralyzed by indecision, but thinking in terms of probabilities is so much more effective than looking for a perfect 'yes' or 'no.' This book is a masterclass in making suboptimal decisions less frequent. It’s dense, it’s data-driven, and it doesn't sugarcoat the hard work required. If you're serious about financial independence, this is a must-buy. It’s rare to find a book that covers everything from credit card debt to angel investing with the same level of expertise.

Ever wonder why some people just seem to make better life choices than everyone else? This book explains the logic behind those 'winners' by using a probability-based mindset. I’ve read a lot of finance books, but Sam Dogen’s approach to the 'happiness equation' is totally fresh. He understands that money is just a tool for freedom, not the end goal. I particularly enjoyed the sections on how to value your time and when to finally leave the corporate grind. The 'Buy This, Not That' framework makes daunting decisions—like whether to buy a fixer-upper or a remodeled home—much simpler. It’s an excellent investment of time. My favorite takeaway was the 70/30 rule for decision making; it has already reduced my anxiety about making 'perfect' choices.

After hearing the author on a few podcasts, I decided to see if the book lived up to the hype. It definitely does. This isn't just about saving pennies; it's a comprehensive guide to building a life of freedom. The deep analysis of real estate versus stocks was particularly eye-opening for me. I’ve always been a stock-only investor, but Dogen’s arguments for the stability of property during downturns changed my perspective. The book is easy to understand despite being packed with data. It’s well-written, punchy, and provides solid guidance on everything from student loans to passive income streams. I also appreciated the 'Financial Samurai' mindset of working hard in your 20s to reap the rewards later. Highly recommend for anyone looking for a modern blueprint for wealth.

As someone who usually finds personal finance books incredibly dry, I was surprised by how much the 'life' aspect of this one resonated with me. Sam doesn't just talk about spreadsheets; he talks about when to have kids, how much to spend on a wedding, and why finding a life partner is a financial decision. It’s a unique perspective that you don't get from Dave Ramsey or Suze Orman. My only gripe is that some of the car-buying rules—like only spending 1/10th of your gross income—feel nearly impossible with today's vehicle prices unless you're buying a total clunker. Still, the logic holds up. The book is well-written and provides solid guidance on everyday topics that most people ignore until it’s too late. I appreciated the chapter on side hustles particularly because it focused on building a brand rather than just trading time for money.

Picked this up specifically for the chapters on career optimization and I wasn't disappointed. The concept of 'income tethering'—linking every investment to a specific life goal—is brilliant and helps keep the motivation high. Dogen's background at Goldman Sachs shows in his analytical approach to risk. He makes a compelling case for 'working while others are sleeping' to get ahead. I do think the book is a bit heavy on the math at times, which might scare off casual readers. I had to read the allocation model chapter twice to really grasp it. But overall, it offers a deep analysis of how to navigate a corporate career and exit on your own terms. It's refreshing to read someone who has actually lived the high-stakes finance life they are advising on.

Is it a math textbook or a self-help guide? To be fair, it's a bit of both, which can be a double-edged sword depending on your patience for numbers. I appreciated the sections on real estate fundamentals and the breakdown of different investment models like the 'Financial Samurai' path. However, large swaths of the book felt irrelevant to me because I’m not planning on having children. The author is very obsessed with the nuclear family structure and 'The Bank of Mom and Dad.' If you're single or child-free by choice, you’ll be skimming a lot of pages. The advice on getting a side hustle is good, but nothing I haven't heard before on various podcasts. It's a solid 3-star read: informative but occasionally narrow-minded in its view of what a 'successful' life looks like.

To be fair, I didn't expect a personal finance book to tell me when I should have kids or how much to spend on a wedding. Some of the personal advice felt a bit preachy, and the 1/10th rule for cars is just plain depressing. I understand the math behind it, but it feels disconnected from the reality of the current market. On the plus side, the chapters on real estate and career strategy were top-notch. I never thought about negotiating a layoff instead of just quitting, and that chapter alone was worth the price of the book. It’s a mixed bag for me. Some of it is visionary, while other parts feel like they’re aimed exclusively at people making $200k+ in San Francisco. Good info, but take it with a grain of salt.

This book feels like it was written in a different stratosphere than the one most working-class people inhabit. Frankly, the author’s perspective is so heavily rooted in his high-earner finance background that a lot of the 'hacks' feel inaccessible. He spends a significant amount of time discussing how to negotiate a massive severance package so you can sail into early retirement. That is great for a tech exec, but how does that apply to a teacher or a retail manager? The advice is technically accurate, I suppose, but it lacks the relatability needed for 'the rest of us' who don't have six-figure safety nets. I found the tone a bit elitist at times. If you aren't already making a quarter-million a year, you might find yourself rolling your eyes more than taking notes. It’s a deep analysis of wealth, just not for the average person.

Honestly, if you aren't pulling in a six-figure salary, most of these 'rules' are going to feel like a punch in the gut. The author suggests saving 50% of your income to reach FIRE, which is a pipe dream for most of America. I also found the section on education a bit contradictory; he says prestige doesn't matter, but then talks about his own elite MBA and background at Goldman. It’s hard to reconcile the 'everyman' branding with the reality of the author's life. The math is sound, but the application is for a very specific demographic of high-achieving corporate workers. I was looking for more 'spending' advice for regular people, but this was mostly about being a landlord and making high-level investments. Not my favorite.
