How do I ask for an informational chat? - 4 months and counting

I sent 8 messages on a professional network and got two replies. It has been weighing on me all week. Some people reply with short answers. How do you phrase the request?

I asked what they wish they had known at my stage. People enjoy answering that.

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