Seized of the matter
The Security Council of the UN often ends resolutions with the obscure phrase, "remains seized of the matter".
Turns out that the entire body is not supposed to debate an issue that's been seized by the Security Council. (Not that the United Nations is a role model for active problem solving… they often do their best work by exhausting everyone instead).
I think it's fascinating to think of issues as being seized. Are your issues being seized by someone else? What happens if you take something off the table and make it yours until it's dealt with?
Most important: how often does kibbitzing and committee-think slow down great work that ought to be seized and shipped instead?
