You gain respect from others who get shit done by getting shit done. It's not just important to hang around folks who do things, you need to participate in the community by doing things yourself.
The advice "hang around people who do things" and "dump people who don't do things" is very much losing the forest for the trees.
I would think this is obvious. To me the biggest part about hanging out with people who get stuff done is seeing what it takes to get stuff done, and then doing that.
Thanks for the feedback.

Alternatively, cool shit might get done. I'd say hang around with people who want to do cool shit and kick their arses into getting shit done if necessary.
