Steve Jobs used to ask Apple designer Jony Ive a simple question:
“How many things have you said no to today?”
That question is a way to ensure you remain focused.
Equally interesting is Ive’s definition of focus:
“What focus means is saying no to something that with every bone in your body you think is a phenomenal idea and you wake up thinking about it, but you say no to it because you’re focusing on something else.”
