You followed the advice. Reach out. Connect. Stay active. Build the network.
And you ended up surrounded by people in your field who are nothing like you.
It's not your fault. The starting point was wrong.
The people who move your work forward are usually outside your category. The author circling the same question from another angle. The researcher ten years deep in a domain you just entered. The practitioner who already failed at the thing you're about to try.
They were never going to show up in a list of people with your job title.
