A phrase I unabashedly derrived fromt he term Cowboy Up, indicating that the person was about to do some hard work. Same thing but for creative endeavors there is less likely to be a physical rammification for a poor performance, but any effort needs to be maxed out.
Only one way I know to burn the candle at both ends, throw care to the wind and get funky with some design. And that, quite simply is to Coffee Up!
Bet you never thought a whole lot of thought went into that did you?
