The problem is that I don't know where to go to network with people, or how to get people to actually find me and my work.
My GitHub is a lonely horse and I think that the only way to actually have an active portfolio on the internet is if you already have an amazing reputation.
I focus by ceasing all communication with the rest of the world. Logging out of your social media accounts and closing anything else that isn't relevant to what I am trying to focus on is a wonderful approach.
