I think content marketing can benefit anyone regardless of their career. I think the same way about sales; we sell ourselves everyday regardless of our profession. If you're a nurse, you are selling yourself to your patients as a trustworthy, knowledgeable health professional.
If anyone else is striving to become a sales and content marketing pro, I suggest you read this book. After I am done with this book, I will be starting a social selling book. Social selling is very relevant in this day and age due to the access of social media. We can now research and contact our prospects via LinkedIn, Twitter, Instagram, etc.
