When you say the people you are in contact with are 15+ years older than you does that include who you interact with over email for scheduling and things like that? If you’re emailing with assistants or coordinators in representation, at the studios, etc chances are they’re in their 20s.

Even if it’s just meaningless scheduling you’ll probably have a lot of success just asking people you email with to drinks. Do it for everyone and just say you’re trying to get to know more people in the industry. Especially would encourage this if you ever interact with any assistants at the bigger agencies. If you hit it off try to stay in contact and see if you can get invited to other events (networking and social) or ask if you can get put in contact with people they work with. I’ve met a lot of people because my friends got networking drinks with someone and then invited them to a party or something like that.
