Warren Buffett Took a Public-Speaking Course, and So Should You One expert-led course is currently on sale in the Entrepreneur Store for less than $20

Considering his indisputable status as one of the most successful business people of all time, you might be shocked to learn that renowned investor Warren Buffett struggled with a debilitating fear of public speaking in his early 20s.

It's true: The now-billionaire used to be so "terrified" of the mere idea of delivering a presentation, "he would arrange and choose his college classes to avoid having to get up in front of people," Forbes notes.

Buffett knew he had to do something about his public speaking anxiety, as such a phobia can have detrimental effects on a person's life. As he explained in an interview several years ago, "If you can't communicate and talk to other people and get across your ideas, you're giving up your potential." (This is especially true in the working world, as studies have shown that "oral communication" and "presentation skills" are among the top attributes recruiters look for in job candidates.)

At some point, Buffett decided to sign up for a professional development course on public speaking to tackle his anxieties for good. His learning didn't go off without a hitch — he actually dropped the class out of fear before enrolling for a second time — but he eventually completed the course, a decision he now cites as a key reason for his profound success.
