Four small (Latin) words that mean so much.
Literally: “Soon nightfall. To the business”.
Or, more colloquially, “Let’s get the show on the road”.
Or, really, Let’s get on with it”.
The point is this. There are a million things we could do today. We could watch TV. We could Twitter. We could check our emails. We could do any number of things that will probably not make any difference to anybody, ever.
Or we could do something that will make a material difference to us or others. Before nightfall.
