In his final interview, Munger discusses the keys to Berkshire Hathaway's success, which he and Buffett achieved together.

• In his final interview with CNBC's Becky Quick, Munger, the former vice chairman of Berkshire, stated that he did not believe we would ever have so many hundreds of billions in Berkshire.
• "It was an amazing occurrence," said Munger.

This conglomerate, worth over $785 billion, has businesses and investments worldwide, surpassing even Charlie Munger's wildest dreams.

"In his final interview with CNBC's Becky Quick, Munger, the former vice chairman of Berkshire, stated that he did not expect to have "so many hundreds of billions" in Berkshire. He added that he did not anticipate reaching $100 billion, let alone several hundred billion."

Munger described the event as "incredible" in a portion of the CNBC interview that aired on Tuesday evening.

Berkshire's largest investments in public companies include Apple, American Express, freight rail operator BNSF, insurance giant Geico, and See's Candies.

According to Munger, the success of he and Buffett, 93, can be attributed to two factors: firstly, their ability to remain sane and focused, which set them apart from others. Secondly, they were granted more time to develop their strategies and achieve their goals due to their longevity. This allowed them to build a long-term track record of success from their humble beginnings.

He also noted both he and Buffett became wiser as they got older.

He explained how we improved our choices and became more aware of the potential risks that can arise, and how quickly they can manifest.
