Legal Issues(can I blog about this)

Hi my name is Sean Nardin. I am a blogger and I wrote about some topics on 'Best Teen Jobs' and I added in sections called. 'What is it" gave a short story. Then continues on to 'The difficulties' of working there. Then wrote on the pay and the time and wrapped it up with a short description of it. All I'm worring about is if I'm allowed to write about those subjects. Ill send a link to a blog and If it's illegal, Ill delete all of them. Here's the link: http://nardin.empowernetwork.com/blog/best-teen-jobs-movie-theaters-the-hidden-treasures I hope you can click on it(if not just copy & paste I guess) I'm just worried if im not allowed to write about this kind of stuff. Thanks.
