A solo service business runs on decisions. Pricing decisions, positioning decisions, sales decisions, client decisions, investment decisions. The quality of those decisions determines the quality of the business. And the quality of decisions is determined almost entirely by the mental models you have available when you need them.
Most solos learn through experience, which is valuable, but slow and expensive. Learning from other people’s experience, compressed into 250 pages, is 10-50x faster. The consultant who reads Gap Selling and immediately understands why their discovery calls aren’t uncovering the right problems has just skipped 2-3 years of trial-and-error learning.
The goal isn’t to read more. It’s to read strategically, a specific curriculum that fills specific gaps, and to apply it immediately. The application protocol is what separates solos who read a lot from solos who get better from reading.
The Curriculum: Category by Category
Sales (3 books)
Start here regardless of how much you dislike the word “sales.” Every dollar you earn as a solo requires a sale. Every rate increase requires a sale. Every retained client relationship requires ongoing re-selling of your value. Gaps in your sales understanding are the most expensive gaps in your business.
Book 1: Gap Selling by Keenan The core idea: people don’t buy products or services, they buy the elimination of the gap between where they are now and where they want to be. Your discovery conversations should be entirely focused on defining this gap in precise, concrete terms. Read this first because it reframes discovery from information-gathering to problem-diagnosis, which changes how every subsequent conversation goes.
Action to take within 2 weeks: Rewrite your discovery call script to include these 5 questions: What’s the current state? What’s the target state? What’s the specific impact of the gap? What has already been tried? What would it mean to close the gap completely?
Book 2: Never Split the Difference by Chris Voss The FBI hostage negotiator’s framework applied to sales and negotiation. The most useful single concept: tactical empathy, understanding the other person’s perspective so completely that you can name their fears before they voice them. The “no-oriented question” technique alone will change how you handle objections. Read this second because it layers negotiation and influence on top of the Gap Selling discovery framework.
Action to take within 2 weeks: Use one Voss technique in your next three client conversations. Start with mirroring: repeat the last 3-5 words of what someone said as a question. Watch how much more information surfaces.
Book 3: Fanatical Prospecting by Jeb Blount The unromantic truth about pipeline: it requires consistent, high-volume activity. Blount destroys the myth of the passive inbound funnel and makes the case for a multi-channel prospecting discipline (phone, email, social, referral) executed on a daily schedule. Read this third, after the previous two give you the frameworks, Blount gives you the activity discipline.
Action to take within 2 weeks: Set a daily prospecting block of 60 minutes, 5 days per week. Track your daily output: number of new contacts reached, follow-ups sent, calls made.
Strategy (3 books)
Strategy books answer the question: what game are we playing and how do we win it? Most solos have never formally thought through their strategy, they drift toward whatever clients appear and whatever services are requested. These three books change that.
Book 4: Good Strategy Bad Strategy by Richard Rumelt Rumelt’s core contribution: most “strategy” is actually a wish list with a budget. Real strategy has three components, a diagnosis of the challenge, a guiding policy for addressing it, and coherent actions. This framework alone will change how you think about your business decisions. Apply it to identify your actual strategic challenge (not “grow revenue”, but the specific obstacle preventing growth).
Book 5: Playing to Win by Roger Martin and A.G. Lafley The P&G CEO’s strategic framework: five interconnected choices, winning aspiration, where to play, how to win, capabilities, and management systems. Translates directly to solo businesses: your winning aspiration (what does success actually look like?), your where-to-play (which clients, industries, and problems?), your how-to-win (what do you do better than anyone in your space?).
Book 6: The Innovator’s Dilemma by Clayton Christensen Read this to understand how markets evolve and how disruption happens. For solos: it explains why being the best at what everyone else does is a fragile position, and why finding an underserved problem in an adjacent space creates more durable advantage than competing head-to-head on quality.
Mindset (2 books, your choice based on your gap)
These are the most personal choices in the curriculum. The goal is to identify your specific psychological pattern that limits your business and find a book that addresses it directly.
Common gaps and corresponding books:
- Undercharging / undervaluing your work: The Art of Asking by Amanda Palmer or $100M Offers by Alex Hormozi
- Avoiding difficult conversations with clients: Crucial Conversations by Patterson, Grenny, et al.
- Procrastination on important but uncomfortable tasks: Eat That Frog by Brian Tracy or Deep Work by Cal Newport
- Inconsistency in self-promotion and visibility: Show Your Work by Austin Kleon
Pick two based on what you know is costing you the most. Read them back-to-back. Apply one behavioral change from each.
The mindset books matter most when you pick them based on honest self-assessment rather than what sounds impressive. The consultant who knows they avoid difficult client conversations but reads a book about growth mindset instead is not fixing their actual problem. Identify your real limiting pattern first, then find the book that addresses it.
Marketing (2 books)
Book 9: This Is Marketing by Seth Godin Godin’s framework: marketing is not about reach, it’s about finding the smallest viable audience and serving them so specifically that they tell others. For solos, the application is positioning: narrowing your focus until you’re the obvious choice for a defined group rather than a plausible choice for everyone.
Book 10: Building a StoryBrand by Donald Miller The framework for clarifying your message so clients can immediately understand what you do and why it matters to them. Most solo consultant websites and LinkedIn profiles suffer from making the consultant the hero of the story. StoryBrand flips this: the client is the hero, you are the guide. Rewrite your positioning statement and website using this framework after reading.
Finance (1 book)
Book 11: Profit First by Mike Michalowicz The single most important financial book for solos. The concept: allocate profit first (take a defined percentage before paying expenses), then operate on what remains. This inverts the typical entrepreneur behavior of spending revenue and hoping profit is left over. The system: four bank accounts, revenue, profit (10-15% taken first), owner’s pay, taxes. Every incoming payment gets distributed according to preset percentages. Apply this within 30 days of finishing.
Free Choice (1 book)
This slot is for a book you’ve been meaning to read, a recommendation from a trusted peer, or a deep dive into a specific area of your business that needs attention. Change it every year.
The Application Protocol
Reading without application produces interesting ideas, not better decisions. The application protocol: within 2 weeks of finishing each book, identify one specific change to make to how you run your business. Write it as a single sentence of intended action. Make the change. Track what happens.
Over 5 years: 60 books, 60 implemented changes. Some won’t stick. Some will transform your business. But the cumulative effect of 60 deliberate experiments compounding over 5 years creates a decision-making capacity that is categorically different from someone who hasn’t done the work.
60 books over 5 years compounds in ways that are hard to predict but easy to recognize in retrospect. The consultant who has read Gap Selling negotiates differently. The one who has read Good Strategy Bad Strategy makes fewer reactive decisions. These aren’t incremental improvements, they’re category changes in how you think about your business.
The 30-Pages-Per-Day Habit
At 30 pages per day, 5 days per week, you’ll finish a 250-page book in under 3 weeks. That’s 17-18 books per year if you hold the habit. Protect the reading block: 25-35 minutes, same time daily, phone in another room. Early morning before checking email or the last 30 minutes of the workday are the two most reliable slots.
The one rule: no new book until you’ve identified and started implementing one action from the last one. Accumulating a reading list without applying is a productivity ritual, not a growth strategy.
