Think about other things you enjoy doing. Are you interested in business? Math? Medicine/health care? There is probably a way to combine it with sports.
There are so many different areas of sports that you can become involved in. Think about what else motivates you and look into that. Do you like building relationships? Are you a good lead? Do you have good negotiation skills? What excites you?
These questions should help guide you into finding a career fit for you.
Once you have these answers, you can do a Google search for jobs related to sports in that focus area. As you examine the companies and the position, see if it fits most of the criteria listed above. Good luck with your job search!
If you want to explore what careers may match with your personality type, I recommend taking a Meyers Briggs assessment. It describes you personality traits and mentions types of jobs that may be a good fit. Of course, your interest in the jobs it mentions is crucial.
