X is for eXecution.
I know, I know... execution doesn't strictly begin with X. Well, once I've worked out how you can use a xylophone to get more done then I'll come back and update this entry; until then it's staying as execution.
"Execution" is the sort of word you only expect to encounter on the powerpoint slide of a high-powered business executive, but it's just a fancy way of talking about doing the tasks on your list.
