MATT:The media world is constantly changing but one thing has remained constant: hard work will get you far and serve you well throughout your career. Hard work can take the form of being a presence at games and practices, reporting on a regular basis, being prepared (a must!), being respectful, and staying in contact with your colleagues who will recommend you to others and/or tell you about opportunities at other outlets.
That's once you get into the business. But how do you do that? It's not easy to get that first job, but there are more opportunities than ever.
So, while you wait for that first job, create your own content! Start a website, produce a podcast, buy a ticket to a game and do some play-by-play from your seats (it worked for Doc Emrick so I think it's safe to say that it's a road to success!). Start the process.
If your high school offers a communications curriculum, take some courses. If you're in college, take advantage of the school's radio or TV station.
And then go back to the beginning of my answer. Work hard!
