I think that segmenting yourself, as in your time, can be useful in helping complete things and give structure. Recently, I’ve found myself getting stuck in “finishing” ruts and it has been difficult to manage everything in the context of other projects, ideas, shows, life responsibilities, etc. The thing that seems to get thrown out most often as it is “lower priority” is making art for the fun of it, and that’s no good, because then I just get tired and aggravated with all the projects that are lining up. I think I’m going to try to set aside a specific day/time a week for doing that.
I think segmenting your “persona” is difficult and complex. I really don’t have a good answer, other than I try to be sort of routine about it, and share the things that I either find interesting and share in the hopes that someone else might find it interesting, or a sense of promoting it out of respect for the venue allowing for the show to be put on, touring acts that might be coming through town and need to pay for gas, etc.
Want to preface this particular point by saying I might be misunderstanding the particular context you mean @eblomquist (and could definitely see how some types of promotion and advertisement can be toxic), but I don’t think it is shameful to promote yourself/your art. I feel like capitalism makes it easy for a lot of us to hide behind a corporation or institution (because it is a normative way to make $$$) and cast a more critical lens onto the ethics of those that are trying to get by/make a living/rely some part on their art.
