Buffett's wealth path:

Wealth was $25 million at the age of 39

Grown 10 times to $250 million at the age of 49

Grown 4 times to $1 billion at the age of 59

Reached $30 billion at the age of 69

$60 billion at the age of 79

$110 billion at the age of 89

The explosion occurred between 1959 and 1969, catching up with the rise of the Internet bubble.

The charm of investing is that people don't need to prove themselves to anyone, nor do they need to argue. If they are really strong enough, they will prove themselves in the market.
