"If you can not communicate, it's like winking a girl in the dark: nothing happens," condemned Omaha's oracle.
Legendary investor Warren Buffett keeps nothing, and he continuously illustrates his followers with their advice to improve their investment and / or increase their wealth.
This time, the Omaha oracle has the recipe for young people to increase their earnings by 50%: focus on learning to write and speaking clearly.
"The only easy way to earn 50% more, at least you need to improve your communication skills both in writing and verbally," Buffett said in a video clip posted Monday at LinkedIn and copied from CNBC's website.
The video that Buffett made the recommendation was posted on Michael Hood's social networking co-founder, Voiceflow, which allows designing, developing and launching skills for Amazon's intelligent spokesperson Alexa without having to know how to encode.
"If you can not communicate, it's like blinking a girl in the dark: nothing happens, you can have all the mental ability of the world, but you have to be able to pass it," says the owner of Berkshire Hathaway.
