Tiny Thoughts

Honesty is discipline when lying is easier.


The most prepared person in the room usually says the least.


We protect money because it’s visible and throw away time because it’s not.

If you burn money, people call you crazy. If you burn time, they call you busy. We treat money as valuable because it’s quantifiable and time as disposable because it’s not.

Insights

Author Esther Hicks on where to look:

“If all you did was look for things to appreciate, you would live a joyously spectacular life.”


Coach Lou Holtz offers 3 rules:

“I follow three rules: Do the right thing, do the best you can, and always show people you care.”


Paul Graham on writing:

“1. When you write something intended to be read by an important person, go through it and cut every unnecessary word. 2. The reader of anything you publish is an important person.“

The Knowledge Project

J.W. Marriott built the foundation of the world’s largest hotel company.

But he didn’t open his first hotel until he was 55.

Everything started with a nine-seat root beer stand in Washington, DC, and a simple goal: serve people well and build something that lasts. And of course, he didn’t just go from restaurants to hotels; along the way, he started the airline catering industry.

This episode explores the timeless principles that guided his success, including his obsession with downside risk, his practice of isolating variables, and his expansion during the Great Depression while his competitors folded.

A few of the Tiny Lessons I took away:

  1. “Manage your time. Short conversations to the point. Make every minute count.”
  2. Take care of your people before your customers. People who feel disposable deliver a disposable experience.
  3. “Guard your habits. Bad ones will destroy you.”
  4. The person who wrote the rule might say yes if you actually show up and ask.
  5. “Discipline is the greatest thing in the world. Where there is no discipline, there is no character.”
