“Find a core set of people that will trust you, and try to build your credibility out from there. Even if you fail to expand from this core, do your best to keep working exclusively or mostly with them. Working with people you trust and that trust you gives a sense of community, and of hope. You will never convince everyone, but you don’t have to, a subset will do.”
This is good advice. Networking is the common recommendation. People talk about how the network helps when other things aren’t working out. I think this is a more direct description of a key part of what to build and how it helps.
