About this quote

Too much time replaying past mistakes or worrying about what might come steals the moments you can actually shape. Do one clear thing today you can finish, however small, and mark it done. Put attention on the person or task in front of you and notice how your mood and options change. Keep this up for a few days and you’ll feel less weighed down by what you can’t change.

When to use it

• At the product stand-up after we missed the release, the manager says, 'Yesterday is history, tomorrow is a mystery — let's focus on the fixes we can complete today.'
• After arguing with your partner at dinner, you tell them, 'Bil Keane said yesterday is history; tonight I'm here, let's talk and be present.'
• Right before a big exam, a student breathes and tells themselves, 'Yesterday is history, tomorrow is a mystery, study this hour and then move on.'
• After a poor training session, your coach tells you, 'Forget the mistakes from yesterday; treat today like a gift and make this workout count.'
