Well done.
I am again reminded, pleasingly so, of Kings exhorting us, the writers, that (in my words), we must find the act of writing an experience in joy. In other words, getting into that flow.
The flow of course has been around for much longer than the fellow you quote. Not to take away from your comment! Rather simply reconfirming that 'flow' or whatever words you choose has in fact been around for ever and is credited for being that thing, one of those things which gives us pleasure.
Thanks for yet another fresh look at the structure. That thing we as writers, or anything else we might do with passion, which propels us into a slightly 'beyond' place and affords us the opportunity to excel.
Now if I could only put myself into that mental hybrid jet! I mean with some regularity.
Thanks again.
