CNBC and Acorns have teamed up to offer workers a helpful tip about self-worth from "Mr. Wonderful" himself, Kevin O'Leary. Kevin suggests finding out where you stand in regards to pay wages compared to your fellow coworkers. If you are receiving less, then Kevin suggests proving to your boss that your work will help the business find success faster. The key to getting more money is to focus on how to make your boss more successful and not yourself, and the rest will come naturally.
