For many people, sports careers offer the ideal opportunity to work in a field they are passionate about. However, it is not enough simply to like sports in order to embark on a sports career - the secret to almost all sports careers is training and qualifications.
Most people choose to focus on a particular sports career - either the one they are most passionate about, or one in which they have a high level of skills. However it is typically not the case that you need to be an exceptional athlete or brilliant at a particular sport to work in that field - most training is more about knowledge and the ability to understand what is involved in working with others than your own level of skill in the sport.
Of course, there are many other jobs that don't involve actually teaching a particular sport - from referees to administrators, events managers to groundskeepers, the range of possibilities is vast.
