Instead of saying “I don’t have time” try saying “it’s not a priority,” and see how that feels. Often, that’s a perfectly adequate explanation. I have time to iron my sheets, I just don’t want to. But other things are harder. Try it: “I’m not going to edit your résumé, because it’s not a priority.” If these phrases don’t sit well, that’s the point. Changing our language reminds us that time is a choice. If we don’t like how we’re spending an hour, we can choose differently.
