This decision rule separates the desire to be right from the willingness to produce a useful outcome. First identify the person with actual decision power and treat that person as the customer rather than assuming logic or status will decide the issue. Then ask whether you are willing, at this time, to make the investment required to create a positive difference. A yes commits you to selling the idea or changing what you control. A no means consciously releasing the topic instead of continuing an unproductive argument. The mechanism converts vague frustration into a present-tense allocation decision.
Origin
Marshall Goldsmith attributes the underlying lessons to Peter Drucker, who taught that the mission is to make a positive difference and that decisions are made by whoever has the power to make them.
Core principles
- 01Making a positive difference matters more than proving you are right
- 02The decision-maker is the customer, regardless of who is smartest
- 03Effort without a realistic path to influence wastes attention
- 04Letting go is a valid decision when the required investment is unjustified
How to run it
- 1
Name the desired difference
State the useful change you want, without framing the goal as winning or proving intelligence.
Pro tip Describe the outcome in terms of what improves for the people involved.
Watch out Do not confuse demonstrating that someone is wrong with making a positive difference.
- 2
Locate decision power
Identify who can actually make the decision. If it is someone else, approach the situation as a salesperson serving a customer.
Watch out Being the smartest or most logical person does not transfer decision authority.
- 3
Price the investment
Estimate the time, attention, relationship capital, and effort needed to influence the outcome now.
Pro tip Include the emotional cost of continued argument.
- 4
Make the present-tense choice
Ask whether you are willing at this time to make that investment. Answer yes or no rather than postponing the decision indefinitely.
Watch out A theoretical willingness someday is not a yes today.
- 5
Commit or release
If yes, sell what you can sell and change what you can change. If no, take a breath and let the topic go.
Pro tip Write down the decision so the same issue does not repeatedly consume attention.
In the wild
Illustrative example: a department head believes another executive chose the wrong vendor. She identifies that the executive owns the decision, defines the operational benefit of switching, and estimates that a short evidence brief plus one meeting could influence it. She accepts that investment, presents the case once, and then respects the decision rather than repeatedly proving her analysis was superior.
→ The issue receives a bounded influence attempt without becoming an endless status contest.
Common mistakes
Treating correctness as authority
A strong argument does not mean you control the decision. Ignoring power leads to frustration and ineffective influence.
Saying no but continuing the fight
If you decline the required investment, repeatedly revisiting the issue defeats the purpose of the rule.
Is it for you?
Best for
It is best for prioritizing contentious issues, influence attempts, and discretionary leadership work.
Not ideal for
It is not ideal for mandatory duties, safety issues, or ethical obligations that cannot simply be dropped.
