Francis Picabia in his studio

If you want to have clean ideas, change them as often as you change your shirts.

Our heads are round so that our thinking can change directions.

–Francis Picabia

Picabia (1879-1953) had a life that included a number of shirt changes. He lived in Paris at a point in time with so many forces were at play, and his friendships were many (including Marcel Duchamp and Gertrude Stein). The evolution of his work speaks to changed directions and changed points of view, from detached Dada-esque mechanical drawings to surrealism to figurative nudes. He also had a Jay Leno-like obsession with cars.

Following the same furrow and deepening the dig has its own merits. But there are times when you have to drop your hoe and leave the task unfinished. Making that call requires some way of knowing when the moment is right. And that it is always an option.
