Do you have sufficient sitzfleisch?

Sitzfleisch is stamina, the power to endure or persevere in an activity. The word is German in origin from sitzen “sit” + fleisch “flesh.” It is a measure of self-discipline, of motivation, and task-oriented drive.

“Literally, the ability to sit, to spend serious time at something, devote your sustained attention to a single subject for four, six or eight hours, and resist the impulse to get up and take a break or check email when you get fidgety or bored.” (The New York Times, May 12, 2012, Tim Kreider, Week in Review.)
