Warren Buffett nearly went bankrupt in 1962
His biggest bet was burning $4M a month. Bankruptcy was weeks away
Then a man named Harry Bottle saved his career in 6 days
The untold story of Buffett’s riskiest investment 🧵
1) Young Buffett thought he struck gold
He bet big on Dempster Mill, a struggling windmill manufacturer
Stock price: $18/share
Book value: $72/share
A 75% discount is the perfect Ben Graham-style bargain
By 1961, he owned 70% of the company
2) But the numbers were lying
Dempster made up 21% of Buffett’s fund
Cash: $166K
Debt: $2.3M
$4M of inventory sat rotting in warehouses some of it since 1909
Bankruptcy was weeks away. Buffett was trapped
Trading in the Zone – Mark Douglas
Most traders lose not because of bad strategies… but because of bad mindsets.
Mark Douglas explains why trading psychology is the real edge.
Here’s the full breakdown 🧵
1)The Core Idea
Trading isn’t about predicting the market.
It’s about learning to:
- Think in probabilities
- Control your emotions
- Execute with discipline
Success = consistency, not prediction.
2) Why Traders Fail
Douglas says most traders fall into 3 traps:
- Need to be right → They can’t accept losses.
- Random reinforcement → A few lucky wins create overconfidence.
- Emotional trading → Fear, greed, and hope drive decisions.
Result: they sabotage themselves, even with good strategies.
This is Mark Douglas.
He wrote “Trading in the Zone” — one of the greatest trading books of all time.
But his live lectures go even deeper.
Here are 11 priceless insights that will instantly make you a better trader 🧵
1. “Anything can happen.”
The market doesn’t owe you anything.
There are no guarantees.
Accept uncertainty — or get eaten by it.
2. “You don’t need to know what’s going to happen next to make money.”
Prediction is a myth.
You only need a repeatable edge and the discipline to follow it.
