A clean sheet of paper
The last few clues on the crossword are the easiest to decode… there aren't as many choices.
Over time, we let the grid at work get filled up, and spend our work day filling in the little tiny corners. We address the undone tasks or find the small improvements that are next on the list.
Sometimes, this tiny incrementalism leads to a big idea. But often, it's the freedom (and fear) of a clean sheet that opens the door to a different path forward.
Of course, the paper is never fully blank. We have countless assumptions about what our assets are, what's achievable and where we're comfortable. These assumptions could be suspended if we cared enough.
The best time to work with a clean sheet is long before you're confronted with one.
