Cold messages to people in my field, do they work? after 14 years as a hotel front-desk agent

I sent 14 messages on a professional network and got two replies. I do not usually post, so bear with me. Some people reply with short answers. What did you ask?

Thanks for writing this out. I went through something close to it 4 months ago, and it settled down once I kept a simple log of every call and form.
