Pushing against something that won't change.

This image is from one of my favourite films: The Tango Lesson by British film maker Sally Potter. Amongst it's many themes it explores the struggle many creative woman face between the cerebral and the physical.

Here is the full poster. I think brilliant.
The painting above which the tango position mimics is Delacroix's Jacob wrestling the angel. A good image for strong women to meditate on when feeling particularly frustrated.
