Guest Introduction and Background
- [01:13] MacKenzie, 26, from Melbourne, FL
- Works: Nail tech (main focus), burrito restaurant, DoorDash, pet sitting, plasma donation
- Describes juggling multiple jobs as “hustling” and using "girl math" to justify business investments
Key Discussion Points & Insights
1. The Reality of Entrepreneurship and the “Girl Math” Mindset
- MacKenzie spent $6,000 (initially claimed $2,000-$4,000) starting her nail salon business, justifying it as an investment needed to make money.
- Caleb directly calls out the lack of planning:
- “There’s no way...That’s an entire year's [worth of profit to pay back your startup costs]...You didn’t have a big supply of clientele...and you honestly weren't doing very well there. You were fired. So great. And you immediately decide, 'Yeah, let me get on this legal contract to split a lease with someone.’” [11:14]
- MacKenzie attempts to defend her approach by labeling it as "girl math":
- "But you have to spend money to make money. In a business standpoint. I call it girl math." [00:45]
- Caleb devastates this logic:
"You're going to make everyone hate women...If girl math immediately—Do you think people don't already hate women?" [50:30]
- The term “girl math,” initially introduced humorously, becomes a running gag and warning of flawed justification for poor financial decisions.
2. Income Streams and Time Allocation
- Breakdown of monthly earnings after thorough grilling:
- Nail business: ~$500/month (about $6/hour for 80 hours; Caleb: “Time to put the nails in the bag, girl.” [12:58])
- Burrito restaurant: ~$1,000/month (best hourly rate—triple the nails gig)
- DoorDash: ~$300-$400/month (after gas)
- Pet sitting: ~$200/month (inconsistent, “most of my clients died” [22:05])
- Plasma donation: ~$550/month
- Total: Roughly $2,550/month before taxes and expenses
- Caleb emphasizes multiple times that gig jobs are not scalable or sustainable, especially compared to a traditional full-time job.
3. Financial Catastrophe: Debt, Overspending, and Lack of Planning
- MacKenzie’s credit cards are maxed out:
- Citi Double Cash ($4,174), IHG ($6,272), Capital One ($2,623 and another card), and Ulta ($491)
- Family/personal loan: $7,500 (for an old car)
- Total debt: About $17,000+, not counting potential family loans and bank consolidation loan
- Bleak commentary from Caleb:
- “You spent four times what you brought in...how do you not know you spent $10,000 last month?!” [24:02]
- “Your business hasn't started. Your business is a failure.” [31:07]
- Budgeting attempts are sporadic and ineffective:
- "Once a month I’ll sit down and write down my expenses, either on paper…” [51:51]
- Caleb: “And then? You just leave it? What does that actually achieve?” [52:12]
- MacKenzie: “I don't have an actual plan. I have no clue what I'm doing.” [27:21]
- Emergency fund: vanished
- Retirement: cashed out 401(k) for a car
- Caleb’s calculation: “That $7,189 would have turned into $212,403 at retirement if left in S&P 500.” [37:24]
- MacKenzie's rationalization: "It wouldn't have done me any good that far down the line if I didn't have a car to sustain." [37:36]
4. Family Dynamics, Entitlement, and Self-Awareness
- MacKenzie receives subsidized housing from friends (“I’d literally be homeless if not for my friends. But I don’t really like living with them.” [29:49])
- Tensions with family about her chosen path—most urge her to get a traditional job, which she resists (e.g., truck driving, supply chain, hospitality)
- Caleb skewers perceived entitlement and lack of appreciation for her circumstances:
- “Median one-bed rent in Mel, Florida is $1,310. Good the luck. And you hate them. You hate living with them.” [31:32]
- Evokes the importance of taking responsibility and strategic career decisions: stick with employment to develop skills and clientele, not impulse entrepreneurship.
5. Repeated Patterns: Justifying Expenses as “Write-Offs”
- MacKenzie claims nearly all spending is a write-off, prompting a signature tirade:
- Caleb: “Also, everything's a write off. On what? You're not making money to pay taxes anyway...what's a write-off to you? What's a write-off if you write it down on paper?” [17:39]
- Attended expensive beauty expos (“business promotion” [52:35]), frequent traveling justified as business/family necessity, when clearly not feasible
6. Future Plans and Relocation
- Considering moving back to the St. Louis area (“to be closer to family,” though admits family won’t let her stay with them due to “family drama” [56:10])
- Talks about wanting to serve drag queen clientele—admits she knows only one in real life
- Caleb: “How many drag queens do you personally know? ... Oh, ladies and gentlemen, it's a foot in the door. This is a thriving small business.” [28:24]
- Caleb provides practical alternatives, including skill certifications and “do the business as a side-hustle only until it’s proven”
- Warns bankruptcy will become the only option if she cannot change her ways

MacKenzie’s story is equal parts cautionary tale and tragicomic, exemplifying the perils of poor planning, magical thinking, and endless rationalization (“girl math”).

For listeners:
- If you recognize yourself in any of these habits, it’s time for a budgeting app, a real plan, and—above all—personal responsibility.
- Skip the “girl math.” Do the real math.
