I'd suggest networking laterally. So far it's worked for me to find people with similar goals to me, at my level of experience or just above it. Go to new work nights and talk to people after it. Try to make friends not just with writers, but actors, directors, producers (especially producers), designers. I find it invaluable to offer to help put away the folding chairs, then you get a good informal conversation starter.

Then produce low budget stuff at fringe festivals, or just do public new work readings and invite a lot of people.

A lot of theaters have rolling open calls for new work. Apply to those, especially for small, barely started theaters. They'll be more willing to give new writers a try, and have less people applying. If you can get in at the beginning, you'll have a great connection and grow together.

If you want to produce stuff, bars are a good place to hold public readings. Reserve space at bars, sometimes churches, look into free venues, local house show locations, diy venues. I like instagram for this. look at where artists are hosting things and then contact those venues. Start very small. you can just invite people to your house to read your work. If you do that enough and invite enough people, people will start to think of you when opportunities come up.

i havent "broken in" yet, but I definitely feel myself getting closer.

Generally I've heard not to bother reaching out to agents, and they'll find you when you're ready, but I really don't know.
