Have you ever wondered how often people change jobs? The number may surprise you. Today, the average person may change jobs 10 to 15 times within their career.

So, if you're considering a professional fresh start, have no fear -- you are not alone. 

In fact, this idea of resetting is something many entrepreneurs think about -- even the most successful ones. If you're looking for wisdom or guidance, here is what some business titans would do if they had to start over: 

Bill Gates says he would devote himself to artificial intelligence, energy, or biology: "The work in artificial intelligence today is at a really profound level," says Gates. "It is going to be phenomenal, so anything connected with that I think would be an exciting lifetime career."

Warren Buffet would keep investing: "I had fun when I was in my twenties, my thirties, and now I am 86 and I am having fun...I would be a failure at anything else, probably."

Barbara Corcoran of Shark Tank fame would start another business: "The minute my rent was covered, I would start a business. It wouldn't make much of a difference if it were a hot dog stand on the corner or a technology startup, as long as I believed wholeheartedly in the product."

Mark Cuban would continue the grind: "I would get a job as a bartender at night and a sales job during the day, and I would start working...Could I become a multimillionaire again? I have no doubt."

Social media maven Tai Lopez would delve into some history books: "First, I would read history. Without a sense of history, you feel like what's happening to you is a once-in-a-lifetime event that nobody's ever dealt with. Understand the great falls others have recovered from."

Craig Handley, founder and CEO of ListenTrust, would reflect and network: "Learn who's in your tribe. Identify your values and have a list of questions to determine if someone shares your vision. Then, spend as little as possible to attend as many events as possible to meet a diverse group of people who could help you. Even sit in the lobby without a pass -- you'll probably get one after connecting with the right people. Be fearless and talk to everyone."

In January 2016, the Bureau of Labor Statistics reported that average employee tenure was at 4.2 years (a decrease from 4.6 years in January 2014). Clearly, starting over is not a taboo thing -- employees (and even employers) are wiping their slates clean every so often, and you can too. So why not give it a go?
