As a coach, there is lots of preparation time behind the scenes that people are not aware of. Depending on what level you coach at, brings various challenges. For example, if your coaching younger sports, you have to conscience of attention spans, weather, and parent interaction, denial and acceptance. Coaching teenagers, you have to deal their peer pressures, and honesty about athletic ability. High School or College, you deal with all as well as ensuring your athletes maintain GPA. All levels your the adult supervisor and have to ensure their well being is cared for. Each level brings in its own difficulty, so you need to have a open mind to all. Its time consuming, but rewarding.
One thing that is often overlooked for coaches, is that although it is a full time job reviewing film, organizing team activities and scouting other teams, it also does give you flexibility in your personal life. You have a schedule that you often set, and as a result, you can work around family obligations etc. Also you are able to shift this schedule around if something comes up, and you have a long off season as long as you only coach one sport. This could allow you to take on a second job, or a part time job or some other form of work to help increase income.
