The smartest people use a simple model and these 6 phrases to say 'no' when they need to, says CEO—here's how it works

• Jot down a few private thoughts about your motives, whether negative or positive. 
• Consider next your recent history of similar yes or no choices. Think about if you’ve volunteered too much in the past and felt a pinch of resentment. Also look for where you may have said no to opportunities that left you curious and hankering for involvement. Let your past experiences play into the choice before you.

• The last step before responding is to consider the future. Project whether your yes or no benefits or harms you or your team days from now. How will your response protect your time and focus? Howwill it impact results? Will it challenge or support your relationships and influence?
• At the base of the Hourglass, it’s time to make your decision and note your considered response. Make a choice, write it down, then deliver it with the confidence bred by the intentionality you’ve shown. (This entire process can shorten to an automatic moment or two once it has become familiar.)

In simple situations, you’ll benefit from the collection of phrases below that can adapt to fit your style.

• “May I take a day to get back to you?”
  Buy yourself time to work the Hourglass. When the interpersonal contact is broken, the intellect engages, better quipping you to make rational decisions.
• “I can do it for you this time, but I can’t do it for you every time.
  Ease a demanding person back slowly from their expectations, and set up a future no.
• “It does not [or will not] work for me to ... ”
  This clause is a marvelous neutral beginning to any no. Be cautious of harshness in your tone

• I can’t, but here’s another option for you.” Share an alternative or suggestion in place of you being able to help.
• “It’s not good for me now, but let’s look ahead in our calendars.” Be careful not to use a delay to avoid a necessary no. Of course, if timing is really the issue, then push the commitment back.
• “Sorry, no.” Yes, this is a complete sentence. Get it out and say nothing more.
