I'm sorry you are struggling with this. It is a contradiction for someone to say that you need to show interest in people but not ask questions!

Conversation is an art, and most people love to talk about themselves. Maybe listening to someone's talk about what they love can be turned to one of your interests by simply asking if they know anything about your interest & then sharing just a little of your vast knowledge, allowing them to ask you questions. It may not be the in-depth discussion you crave but it will be a start.
I wish you all the best....
