Corporate Communications Pro
I've spent more than 20 years in a PR career and have enjoyed most of it, so I'll never bash the field and would never discourage someone from pursing a career in PR.
At the same time, PR encompasses so much more than "people and planning" and I'm afraid that too many young people have an image of the industry that comes from TV and movies that isn't always indicitive of the broader industry.
Some things to think about:
Do you like writing? A lot of PR work on a daily basis is about writing. You'll write press releases. You'll write content for social media platforms. You'll write plans. You'll write articles... I think you get the point. It's a lot of writing.
Can you handle rejection? PR is a lot like sales. Reporters will tell you "no" all the time. Or they won't even respond. Or your client won't like the release you wrote or the plan you submitted. It doesn't mean the work wasn't good. It just means that you need to go back to the drawing board. Being able to take negative feedback in stride and keep plugging away is crucial.
Are you flexible? Can you go with the flow... or are you more of a rigid personality type? Practicing PR requires someone who can be fluid and adapt to rapidly changing situations without getting flustered.
The last thing to think about is that studying PR does provide a lot of skills that can be applied to other fields. You'll learn critical thinking. You'll learn to be a better writer. You'll learn to be a better storyteller. Etc., Etc., Etc. So, if you think it's a potentially good major for you, I'd say go for it. You'll be able to take those skills to a lot of different places even if you don't end up in a career in PR.
