Every yes is a no to something else.
Focus isn't what you choose to do. It's what you choose not to do, and saying so out loud.
Four Questions Before Any Yes
Does it serve our strategy?
If not, it's a distraction, however good the idea.
Is it for our best-fit customers?
Or for someone we've decided not to chase?
Is it the best use of the team now?
Compared with what's already on the list.
What will we stop to make room?
If the answer is “nothing”, the answer is no.
“Not now” is a strategy too.
