once a man i knew told me “you write books, i have an idea for a book” and spent 20 minutes telling me an absolutely insane thriller plot, i was really into it, advised him to write it, he said he lay awake at night thinking about it, but then it turned out the whole thing was due to a brain tumor
the idea phase is the easiest and least valuable part of professional creativity. read the first draft of the first Star Wars if you doubt me Great art is made in the grinding, often miserable collision between the ethereal substance of an idea and the mud and blood and friction of reality
