I’ve heard this sentiment expressed in different ways for startups.
“Focus”
“The OMTM” (one metric that matters).
At SydStart today (Sydney’s biggest startup event), it was repeated in a way that somehow stuck with me:
Find the one thing you can be the best at globally. Make sure everyone on your team fully believes it. Then pursue it at the expense of anything else. – Dominic O’Hanlon
Thinking about it this way just raises the bar.
A startup may have found its ‘one thing’, but if a dozen other companies can do the same or better, it’ll never make a dent.
