what does it mean to lose one's self in creativity?
I heard Jane Hirshfield’s interview also, the one with Sam Harris. It’s so apparent. I’m only a cook when I fry an egg. I’m likewise a writer when I engage in that work. To replay Buckminster Fuller’s dictum, “I seem to be a verb.”
Flow, I think, is almost innate in someone who creates. it doesn't mean it there all the time, certainly. But it's an element of an artist's (in all that means) DNA. I love that you didn't mention "inspiration" or link it to flow. If a writer or poet or artist of any kind is waiting for "inspiration" to move you to create, you'll be waiting a long time. The work is a craft. Get to work. But leave yourself open for the "flow." When it comes, ride it. Be Dr. Dre whenever you must.
