While I'm in the camp of writing everyday, there's more to being a writer than just getting words into a page.
Along with honing the skill set of technical proficiency (Grammar, imagery, solid vocabulary, etc.). I believe you can also spend productive time learning Story craft (Differences in Genre, Tropes and conventions, Plot and Story Archetypes, etc.). There is a significant difference between the two.
And that's just academic stuff. Also to read widely. Both in your genre and out. We fill our creative wellspring with experiences AND the stories we expose ourselves to.
So movies, plays, shows, and especially books we love can provide us with motivation, inspiration, and just remind us to enjoy stories. We write because we have something to say. We get blocked when we don't know what we wanna say.
For me that's all inspiration is: Knowing what you want to say. Not necessarily in words, sometimes it's just a feeling. But what's most important is that its clear to you.
Stories cannot be written out of the void imo. Art reflects life. And Art reflects it's creator and how they see the world, how they think about the world.
One advice I like comes from Stephen king. Paraphrasing, he's said that a writer who doesn't have time to read is not a writer. If you're serious about writing, you have to know about your given medium and field.
I work full time in comics so I'm largely an artist. But i still count myself as a writer because I'm learning to be proficient in scripts and telling stories through dialogue and the subtext of writing a plot that ultimately has to be shown visually. When i don't have inspiration to work on the script, it's usually because my creative wellspring is dry.
When that happens I try to do something writing-adjacent: read novels, study screenplay and storycraft, watch a movie or show with an eye to how the plot and dialogue are done, and so on.
OP, when you mentioned shifting your life to accommodate writing, I agree completely here. Good writers make space not only to do the act of writing, but also the act of enjoying others writing.
