What is a one-sentence summary of the following article?
There are three primary career fields for sports psychologists. Which field you'd like to concentrate in will determine the focus of your studies and the scope of your internship/work experience. The three fields are:  academic jobs - teaching sports psychology coursework and conducting research at a university applied psychology jobs - training athletes and working with entire sports teams to enhance team performance, motivation, and endurance  clinical psychology jobs - working one-on-one with athletes and coaches to teach coping skills, work through stress and performance anxiety, and address any underlying psychological issues Some degree programs require an internship as a mandatory part of your education, and for good reason. Internships are an excellent way to gain experience in your field, add credentials to your resume, and make network connections that could last a lifetime.  Try getting involved in sports, or at least following a team and learning the basics of the game. You'll ideally be working with athletes, so it's best to understand what athletes go through on a daily basis.  Your college/graduate/doctoral program may offer specialized internships through some type of partnership. You can find internships by reaching out to a practice you'd like to work with, or by searching the APA website for internships in your area. Professional organizations are not a requirement for work in sports psychology, but they can help you build professional contacts and may open new career doors to you down the line. Some of the most common professional associations for sports psychologists include:  Advancement of Applied Sport Psychology (AASP) American Psychological Association (APA), Division 47 International Society of Sport Psychology (ISSP) North American Society for Psychology of Sport and Physical Activity (NASPSPA)

Summary:
Choose an area of concentration. Take an internship. Join a professional association.
