I read somewhere this week that inspirations come from/through working; it was attributed to a well-known artist, but I can't remember to whom, or where I read it.
When I stick to one (or two or three) idea and keep working and developing it, I come up with what some may call inspirations which are like a leap in a step or thinking process. These, to me, are fruits of hard slog, so on the appreciation scale, they are between 60 and 75 out of 100.
Sometimes the physical motion of work, like warping, weaving or even ironing, brings on certain inspirations, and though I appreciate these, I have to interrupt whatever I'm doing to write these down. 25-85/100.
By far my favorite are the ones coming out of nowhere; the "a ha!" experiences. These are like gifts, free of cognitive charges. Sometimes these connect dots I hadn't noticed should/could be connected, sometimes they come from so far out the left field it's outside the ballpark, and I wonder about the origins for days, years.
I've had to learn to leave room for these spectacular gifts, and that was a hard slog. But sometimes I have the room now.
