The best books on financial independence and FIRE (Financial Independence, Retire Early) are less about any single investment and more about a change in how you treat money that compounds over years — which is exactly the mindset that also makes a cash-flowing side business like a vending route worth building in the first place.
These seven show up constantly in FIRE communities for a reason: each one carries one specific, usable idea rather than a pile of generic saving tips. Read them in whatever order matches where you are — the first two if you are just getting the concept, the middle ones once you are actually saving and investing, the last two once you are close enough to think about the transition.
#1
Your Money or Your Life
by Vicki Robin & Joe Dominguez
Best for: Someone who has never actually calculated what an hour of their income costs them in hours of their life.
The book’s “life energy” framing converts every purchase into the number of working hours it actually cost you (after taxes, commute time, and work-related spending), which is a genuinely uncomfortable exercise the first time you run your own numbers through it.

Worth knowing: Some of the specific investment advice is dated (it predates low-cost index funds becoming the default), so pair it with a more current investing book for the mechanics.

The Simple Path to Wealth
by JL Collins
Best for: Someone who wants the case for “just buy a total market index fund and stop overthinking it” made in plain language, with the reasoning shown.
Collins builds the case for a single low-cost total-market index fund (originally written as letters to his daughter) around avoiding debt, minimizing fees, and staying invested through downturns rather than trying to pick winners — and he is explicit about why simplicity beats complexity for most people.
Worth knowing: It leans heavily on one fund family and the U.S. market; if you want a broader look at portfolio construction or international diversification you will need another source.

Set for Life
by Scott Trench
Best for: Someone earning a normal income who wants a concrete early-savings plan rather than a philosophy.
Trench’s central target is getting past what he calls “the wall” — the first $1,000–$2,000 a month in passive or semi-passive income that makes every financial decision after it easier — with specific tactics around housing costs, which are usually the single biggest lever most people ignore.
For a vending operator: A cash-flowing route is a plausible way to cross exactly the kind of income wall this book is about, alongside the housing-hacking tactics it focuses on.
Worth knowing: The housing-focused tactics (house hacking, aggressive rent reduction) assume flexibility on where and how you live that not everyone has.

Die With Zero
by Bill Perkins
Best for: Someone deep into the saving habit who has never seriously questioned whether they are saving past the point it still helps them.
Perkins argues most people over-save relative to their actual life expectancy and end up with unspent money and unused time in the same years — his “net worth curve” framing is a direct challenge to the FIRE community’s own instinct to keep accumulating past the number that was originally the goal.
Worth knowing: It is a useful counterweight to pure accumulation, not a replacement for it — read it after you already have a savings habit, not before.

Quit Like a Millionaire
by Kristy Shen & Bryce Leung
Best for: Someone who wants to see the FIRE math actually applied by two people who retired in their early 30s, mistakes included.
Shen and Leung walk through their own numbers — the exact savings rate, the specific market crash they retired into, and how they adjusted spending in response — rather than presenting FIRE as a clean, risk-free formula.
Worth knowing: Their extremely high savings rate (over 50% of income for years) is not achievable for most household budgets without either a high income or a spending level not everyone wants.

The Bogleheads' Guide to Investing
by Taylor Larimore, Mel Lindauer & Michael LeBoeuf
Best for: Someone who has decided to invest and now needs the actual mechanics — account types, asset allocation, rebalancing — explained without jargon.
Named for Vanguard founder John Bogle, the book lays out the case for a simple, low-cost, broadly diversified three-fund-style portfolio and covers the practical account-type questions (401k vs. IRA vs. taxable) that more philosophy-focused FIRE books skip.
Worth knowing: It is a reference and a how-to, not an inspiring read — useful once you are ready to act, less useful if you are still deciding whether to.

Rich Dad Poor Dad
by Robert Kiyosaki
Best for: Someone who has never separated the idea of “an asset” (something that puts money in your pocket) from “a liability” (something that takes money out), regardless of what it looks like on paper.
Kiyosaki’s asset-versus-liability framing — judged by cash flow direction, not by what conventional accounting calls an asset — is the book’s one durable idea, and it is a genuinely useful lens for evaluating a vending machine, a rental property, or a car the same way.
For a vending operator: By this definition a well-placed vending machine is a textbook asset: it puts money in your pocket every month after the setup cost is behind you.
Worth knowing: Several of the book’s specific stories and investment claims have been disputed over the years — take the asset/liability framework and leave the specific real-estate and stock anecdotes for independent verification.
