Be quick to say no and slow to say yes

Be quick to say no and slow to say yes. Saying yes consumes time, saying no creates time. Never say yes on the spot. Always give yourself some space. Make it a rule. Tell people. That’s what Daniel Kahneman does. When he’s on the phone he says ‘my rule is I never say yes on the phone. I’ll email you later after I think about it more.’ And when I asked him how often he later says yes, he responded ‘rarely.’
