However, there are ways to prepare. The most powerful way is by investing in your personal brand. More than just tweeting occasionally or grabbing the first endorsement deal you see, your personal brand is about gaining fans outside of your sport, as well as in it.
You can do that by sharing your whole, authentic self. By valuing other areas, in addition to your professional or athletic side, you can gain fans in many different arenas. This means that you have other areas you can show your expertise and enthusiasm. And when your career ends, you're set up for the next step.
Hop on a podcast to discuss your years of go-kart racing. Share a recipe for cajun food that you've honed over the years. Tweet videos of your efforts to teach your children Mandarin. You are more than your job, and sharing that with the world will allow you to connect with new audiences you never thought possible.
