Write, write, write! Being able to concisely communicate ideas in a compelling manner is the most important fundamental skill in public relations. Anyone can become a better writer through practice, so look for opportunities to help you improve. Many small local newspapers and online publications will let high school and college students write for them. If you join an organizations or club, you can volunteer to help write the newsletter. While I was in college earning a degree in journalism, I wrote for the student newspaper and student-produced TV news show, interned with a news station and put together a newsletter for a nonprofit, all of which helped me get a job in PR. Write and read as much as you can and you'll be better prepared for any career you choose, even if you don't end up in PR!
