Peter Buffett, son of billionaire Warren Buffett, once said his dad was “socially inept” as a young man, and, “in large crowds, he’d much rather not be there.”

In that same piece for the BBC, the elder Buffett, now perhaps the most often quoted figure in all of finance, acknowledged his intense fear of speaking in public early in his career. “I couldn’t do it,” he said. “I’d throw up, and everything.”

At that point, he took it upon himself to tackle his shortcoming head-on, and the rest is Wall Street history, billions of dollars later.

So, it should come as no surprise that this is the answer the Berkshire Hathaway BRK.A, -2.85% BRK.B, -2.75% boss recently gave when asked for one tip for youngsters graduating college:

‘The one easy way to become worth 50% more than you are now, at least, is to hone your communication skills — both written and verbal.’

Buffett went on to add some of that trademark Buffett folksiness to the conversation: “If you can’t communicate, it’s like winking at a girl in the dark — nothing happens,” he said. “You can have all the brainpower in the world, but you have to be able to transmit it.”

The exchange was posted on LinkedIn by Michael Hood, a 22-year-old entrepreneur, who, according to CNBC, was escorting Buffett to the Canadian Walk of Fame Inductee Gala on Saturday.

Hood, co-founder of Toronto-based Voiceflow, was chosen for the “once-in-a-lifetime opportunity” by startup incubator Next 36, he told CNBC.
