How do I ask for an informational chat? - first time posting

I want to talk to people in a new field but I hate cold messages. There are 13 people counting on me, so I am trying to be careful. I want advice, not a job directly. What did you ask?

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.

I wrote three short lines: who I am, why them and a small ask for fifteen minutes. About one in four said yes.
