Looking to Revamp My Career. What Are My Options?

I have been a freelance writer in the B2B/marketing niche for the past three years. Prior to that, I have worked as a marketing manager.

I am feeling like I am stuck in a rut doing the same type of work and looking to expand my options. I am thinking of getting into product marketing, product management, or development (front-end or full-stack web).

Getting full-time into development would bring me back to square one and I am not sure if I can manage to that at this stage. However, I feel having these skills would be a great add-on.

Would really appreciate the community's advice on what I can do to get into product marketing/management?
