In one sentence, describe what the following article is about:

Clear your mind of the stress leftover from your job. If you do get fired, you'll have plenty of time to focus on what makes you happy. You'll get to learn new things about yourself and reassess your career goals. You may find that you want to do something entirely different than the position you were let go from. Focus on your health. Make an exercise routine. Adopt a healthy diet. Get plenty of sleep. Have new experiences. You can enjoy inexpensive adventures like going hiking. Learn new skills you never had time for while you were working. Enjoy some quality time with your family. Being overly focused on work can make you forget the things in life that are really important. If you get fired, you'll have a lot of extra time to connect with your kids, your spouse, your parents and whoever else is an important part of your life. Many of the most successful people in our country have been fired. Sometimes, being fired from a position that doesn't fit you can lead to you finding your true calling. J.K. Rowling was fired from her day job as a secretary and was even homeless for a short period of time before writing the "Harry Potter" books. Michael Bloomberg was fired from an investment bank and used his severance package to start his financial data company. Bloomberg L.P. is now one of the most successful companies on the planet. Having constant fear that you'll be fired can be very detrimental to your self-esteem. When you're out of that job, you'll get a chance to remember how great of a person you really are. The only thing that changes when you get fired is your employment status. You'll find that you're still the same intelligent, capable person you were before you worked there and eventually another company will agree.
Spend time getting to know yourself. Spend some time with your loved ones. Look up stories of people who succeeded after being fired. Get your confidence back.
