I was playing Civilization V, and had just finished reading Cicero, by Anthony Everitt.

Cicero had done so much in his lifetime, and I was sitting around watching time disappear six-hour-chunk by six-hour-chunk, with nothing to show for those hours spent.

It was one of those anxiety filled: there's-so-much-I-don't-know-and-I'm-wasting-so-much-time moments.

Thanks for asking!
