Become a fitter founder in 7 days.

One of the worst sentences in the English language: “in another life.” The admission that you gave up on a meaningful life without ever trying.

Ray Kroc was a 52-year-old milkshake machine salesman dealing with diabetes and arthritis. Not exactly something that impresses the in-laws at Thanksgiving. He could have called himself too old and quietly quit.

Instead he found the McDonald brothers' restaurant in San Bernardino and built it into the $200B+ empire it is today.

Today's lesson: It's never too late to change your life and build founder fitness.

Sarah bounced around foster homes in Boston. While she worked at a diner, a wealthy childless couple who were regulars decided to pay her way through college.

She finished a business degree wanting to buy a business, with zero clue how. So she turned the college library into an office, filled it with interns, and cold emailed her way into a meeting with the owner of eggcartons.com.

With little savings, she got the banks and the seller to finance the deal with almost nothing down. The business passed $10M a year in revenue in 2024.

Today's lesson: There is unlimited upside for those who refuse to accept the cards they were dealt.

Social media makes us forget it, but building a company is hand-to-hand combat, especially early. Even for the founder of Nike.

Phil Knight sold shoes from the trunk of his car at track meets. Then it got worse: sketchy credit lines that risked bankruptcy every payroll, a key supplier that tried to cut him out, and a years-long fight with U.S. Customs that nearly sank the company.

He stayed founder and CEO for 40 years. Marcus Aurelius had it right: the obstacle is the way.

Today's lesson: Becoming a fitter founder isn't linear. Expect obstacles, control what you can each day, and let it compound.

Nick Mowbray went to China with no money, no plan and no language. He slept in a bush outside the airport, built his own factory when no manufacturer would work with him, and lived on about $1 a day for years.

When lawsuits hit or purchase orders died, he found new products and new markets. He made small batches of toys, tested them at trade shows, killed the flops fast and poured money into the winners. ZURU is now one of the most profitable toy companies on earth.

The point isn't to move to China. It's to fear not trying more than you fear failing.

Today's lesson: Don't fear failure. Fear not acting.

Before SPANX, Sara sold fax machines door to door in the Florida heat, six days a week, to receptionists trained to say no. It taught her clear messaging and how to take rejection.

She cut the feet off her pantyhose before a party and the idea stuck. With $5,000 and no fashion background she called factories until one owner said yes, then talked her way into ten minutes with a Neiman Marcus buyer and closed her first order in the meeting.

The Oprah moment that made SPANX famous came after five hard years.

Today's lesson: Create your own luck. When someone says it isn't possible, ask “why not?” and then ask for something smaller.

Before Canva was worth over $40B, Melanie Perkins and her team were turned down by more than 100 investors.

Instead of taking on Adobe, she started narrow: Fusion Books, a yearbook design tool that proved non-designers would create when given smart defaults. After each rejection they didn't add features. They removed steps, which made the product faster and the pitch tighter.

Seneca wrote that difficulties strengthen the mind, as labour does the body. Those rejections built the company.

Today's lesson: Constraints produce clarity. No pile of investor cash forces you to build something profitable from day one.

Jan Koum grew up in Ukraine in a house without running water. In the U.S. he swept grocery store floors, relied on food stamps, and taught himself to code from second-hand books. Facebook turned him down for a job.

He didn't reinvent social networking. He built dead-simple, fast, private texting that worked on any phone and any network, and kept removing steps, settings and screens. Founders answered support emails. Outages were treated as existential.

WhatsApp spread worldwide, and Facebook fixed its hiring mistake with a $19B term sheet.

Today's lesson: You're probably overthinking it. Make your business so simple a stranger gets it in two minutes. (Not your mom. She'll say it's great anyway.)
