This is more a money mindset book, how to reframe your relationship with money, than a book that actually teaches you about financial strategies and jargon.
As someone who ascribes to a minimalist philosophy in mind and spirit, in addition to physical wealth, I really dig this book. It's not a one-size fits all solution to getting rich; it's about identifying what you value in life and for your future and making sure that the way you spend your money aligns with what you value. Values and alignment. It doesn't get better than this.
Furthermore, there's just some really great life advice here that echoes a lot of valuable lessons I've learned in a recent personal development academy and are really relevant to my own areas of improvement. Things like, "Don't worry about getting it 'right.' You can--and should--simply course-correct your guess when you notice yourself going off track." Or, this can apply to much more than finances, "Give yourself permission to use the past as a springboard to save more, not a billy club to hit yourself." And this really resonates with me, "When we have to prioritize our goals, many of us become paralyzed, and as a result do nothing."
One point Richards makes, which totally makes sense to me, is to see things from the perspective of what you gain, rather than what you lose. I've been gawking at a pair of earrings at my retail job for weeks now. Love them. I could make up a million stories of why I should buy them (they look great on me, I don't have any earrings and it would be nice to have them for special occasions, I get an employee discount, etc.). However, when I think about my values--travel, time with loved ones, environmentalism, saving for a comfortable and early retirement--I'm suddenly not drawn to the earrings anymore. They don't serve any of those values, and that makes it so much easier to walk away without purchasing them.
Also, this 100% confirmation bias, but Richards echoes what I know about diversified portfolios, index funds, which just makes me trust him more. You won't ever find me following the advice of people who speculate on single companies or sectors and call that "investing..."
I do wish there were a worksheet or checklist at the end to complete all the steps, or some way to organize action items. I read this all at once before doing all the steps, and now I've got to go back and find all the action items.
