Inspiration rarely shows up at its designated appointment time.
It ignores anyone’s summoning, much like a teenager ignoring demands to be home at a certain time.
It knows you’re around, but makes no effort to join you.
Expecting it to turn up when you want is a futile effort. it loves its freedom and will have no part in sacrificing any of it.
It’s aware of its power and enormous benefit to your work. However, it cares for none of the responsibility to deliver an inkling of usefulness to you.
It cannot be forced.
However…
If you keep the invitation open…
and let it know where you’ll be every day…
and work without expectation of it showing up…
it tends to join you.
