You blow the presentation and spend the drive home scripting perfect comebacks to an audience that’s already gone. Your relationship ends, and you spend months replaying conversations that can’t be changed. All the time spent perfecting the past is stolen from the future that’s still waiting.
Focusing on past accomplishments creates obstacles to success in the present. If you're still talking about something great you did 20 years ago like it was yesterday, your ego is getting in the way.
What you did in the past makes a good story. What you're doing now makes a difference.
