By now, you’ve probably heard that global supply chains are in a state of disarray.

Here's a simple breakdown of what’s causing it: Image
1/ There's a lot of talk right now about the global supply chain crisis.

@business published an article subtitled "Inside the Brutal Realities of Supply Chain Hell”—it's getting serious.

This thread provides my (very) simple framework for understanding the key drivers:
2/ First off, what are the visible impacts of the crisis?

Product delays (good luck getting appliances before 2022), product shortages (see semiconductors), port buildups (fly over LA and you'll see), and rampant freight costs (sorry, retailer margins).

It's pretty bad. Image
3/ Global supply chains are very complex. We live in a highly-interconnected world.

A butterfly flaps its wings in Shenzhen and impacts when I receive my bike in New York. Ok, maybe not quite, but almost...

So to understand the drivers of the crisis, we need a simple framework.
4/ Let's break down what is happening using an Econ 101 classic: Supply and Demand.

Supply here refers to everything related to manufacturing, production, and transportation.

Demand here refers to everything related to consumption.

I'll walk through each side:
5/ First, demand. This one is pretty simple: it's through the roof.

Consumers are flush and not afraid to spend.

Further, lockdowns and restrictions have meant more spending on goods vs. services.

So you have a ton of demand for goods--those goods need to come from somewhere!
6/ Next, supply. This one is more nuanced.

The major supply drivers I see here:
(1) Factory shutdowns
(2) Port shutdowns
(3) Flight reductions
(4) Container ship challenges

Hitting each one quickly:
7/ COVID Factory Shutdowns

Factories—particularly in Asia—have had a tough time managing and containing outbreaks of COVID.

This leads to delays and bottlenecks in production. If an upstream manufacturer is delayed, that impact cascades downstream and has an extensive impact.
8/ COVID Port Shutdowns

Ports have experienced similar challenges—any have had to shut down or restrict labor to avoid outbreaks.

If ports are closed, products can't flow smoothly through the supply chain.

It's like creating a kink in a hose and watching pressure build. Image
9/ Flight Reductions

It's news to most people, but about 50% of air cargo flies on passenger flights.

It's a great revenue stream for passenger airlines.

But with travel—especially international travel—reduced by COVID, there was a significant reduction in air cargo capacity. Image
10/ Container Ship Challenges

The Ever Given clogged the Suez Canal in March, causing a backlog whose impact cascaded through global supply chains.

There aren't enough large container ships to meet all of this demand and containers are in the wrong places at the wrong times. Image
11/ So looking at all of this through my simplistic framework, here's what I see:

On one end, a structural surge in demand for goods.

On the other end, a number of significant supply challenges and disclocations.

Demand up, supply down.
12/ The net impact: sharp shipping and production price increases, shortages, and massive delays.

For consumers, this means rising prices, as these rising supply chain costs are passed through.

Your holiday shopping may be a whole lot more expensive (and late) this year... Image
13/ I hope this simple breakdown helps you feel more well-informed about what is happening with the global supply chain crisis.

Looks like a lot of people are flocking to Evergrande offices to take advantage of this limited time opportunity! Image
There are a few other supply-side factors that folks correctly mentioned that I will plan to cover in my newsletter piece tomorrow.

• Labor Shortages
• Infrastructure Deficiencies

In 2009, Stanford business professor Tina Seelig split her class into groups and issued a challenge:

Each group had $5 and 2 hours to make the highest return on the money.

At the end, they'd give a short presentation on their strategy.

What happened next was fascinating: Image
Most of the groups followed a simple approach:

• Use the $5 to buy a few items.
• Barter or resell those items.
• Repeat
• Sell final items for (hopefully) more than $5.

These groups made a modest return on their initial $5.
A few groups ignored the $5.

They thought up ways to make the most money in the allotted time:

• Made/sold reservations at hot restaurants.
• Refilled bike tires on campus.

These groups made a good return on the initial $5.

The winning group took a very different approach:

Here's the secret of the most charismatic people in the world...

The 3 Levels of Listening: Image
I used to think that being charismatic meant talking the most.

I was wrong.

Charisma is about being interested, not interesting. Charismatic people are present and engaged.

They are exceptional listeners.

I recently learned that there are three levels of listening:
Level 1: "Me" Listening

You're in a conversation, but your internal voice is relating everything you hear to something in your own life.

Your internal voice runs off on tangents while the other person is talking.

You're waiting to speak.

This is the default mode of listening.

Your entire life will change the moment you…

Stop gathering more information and start acting on the information you already have.
Your entire life will change the moment you…

Stop complaining about things you can’t control and start taking ownership over the things you can.

I can't stop thinking about this idea...

The 3 Types of Friends:

(everyone should read this) Image
The idea originates from Tyler Perry (portraying his wise Madea alter ego).

It's a brilliant framing for thinking about your relationships.

There are three types of people in your life:

1. Leaves
2. Branches
3. Roots

Here's what they look like...
LEAVES

These are the people that are only around from time to time when the weather is good.

They blow around as the winds change.

They provide shade during the summer, but as soon as winter comes, they fall off the tree and disappear.

The secret to success that no one tells you about...

Avoiding the Compound Mistake:

(thread) Image
Let's begin by referencing the image made famous by Atomic Habits.

While most of the dialogue focuses on the 1% better every day, which results in a ~38x improvement, the 1% worse every day is just as important:

It effectively zeroes you out—it knocks you out of the game...
When I was playing baseball at Stanford, the coaches had a metric they liked to track for pitchers called the Compound Mistake.

The idea was simple: Image

I challenged myself to cold plunge every morning for 100 straight days.

- Three different continents
- Several frozen rivers and lakes
- Dozens of hotel bathtubs
- One icy shower at 40,000 feet

10 lessons learned from 100 days in the cold:

(a video thread) Image
Lesson 1: Discipline is about what you do on the days when you feel like crap.

It's easy to be disciplined and consistent when you feel great.

It's hard when you feel like crap.

Those are the days when you remind yourself that you are a winner.
Lesson 2: Stop overthinking, just start.

"No plan survives first contact with the enemy."

Too many get their dopamine from the planning. Too few get their dopamine from the doing.

Plan a bit, then make first contact with "your enemy" and start improving fast.
