Warren Buffet's formula for success is based on making good investment decisions. Investing might not be about money choices. He once said that investing in yourself is the best thing you can do. Anything that makes you a better person.

What is a good place to start investing in yourself? There's a simple strategy that Warren Buffet always follows: go to bed a little smarter each day.

TheOracle of Omaha spends 80% of his workday reading and thinking to gain an enormous competitive advantage.

In the past, Buffett has said that investing in developing your communication skills can improve your value by 50 percent.

If you can't communicate, it's like winking at a girl in the dark--nothing happens. You can have all the brainpower in the world, but you have to be able to transmit it. And the transmission is communication.

The billionaire has admitted that he used to be terrified of public speaking, and threw up. He said that after he took a public speaking course, his life changed.

Business owners and leaders are told many times that they need to improve their communication skills in order to succeed. If we want to grow our businesses and ourselves, we need to pay attention to it.

The American Journal of Small Business wanted to find out what small-business owners thought were the key factors in successful entrepreneurship. Listening and oral communication were cited as the top two characteristics. There is an area of communication that is severely lacking in remote settings.

We have to pay attention to our writing ability because that matters as well. According to a study by the National Commission on Writing, American businesses spend 3.1 billion dollars a year on training to write. Eighty percent of finance, insurance, real estate and services assess writing skills during the hiring process.

Bob Kerrey said that writing is a marker of high-skill, high- wage, professional work. People can't express themselves clearly in writing so they can't get a job.

Warren Buffet's lifelong pursuit of investing in himself and his communication skills should be an example to leaders and entrepreneurs around the world. It could be the secret to his success.
