Was it Einstein that said he got his greatest ideas and “ah-ha!” moments while shaving?

I get moments of clarity while showering.  I’m by myself, free from the demands of attention from email, cell phone, people, etc.  I’m only there to do one thing, and the hot water feels so relaxing.  Those moments as my hair soaks up and my skin dampens, it’s just me and my thoughts.  And they aren’t forced.  There’s no expectation of productivity (other than to wash up) when I hop in the shower, and therefore no barriers to creativity or “ah-ha!” moments.

Maybe it’s a function of the water, too.
