The next time you ask someone to rate something out of 10, tell them they can’t pick 7. Seven doesn’t give you enough information. If it’s an eight, it’s desirable; If it’s a six, it’s not. Seven may or may not be worth it.
So instead of letting the person come back to you with an un-definitive 7/10, force them to bump it up to worthy or bump it down to un-worthwhile.
Not sure if this is helpful? Then let me ask you: On a scale of 1 to 10, what’s this advice worth to you? … and of course, you can’t pick 7!
