There is a rule that has helped me put failures and victories into their proper perspectives.
The 24-hour rule states that you turn the page every day. No matter what. You can celebrate or cry but tomorrow you turn the page. Tomorrow is a new day.
We all know the person at the office that hangs on to the past. They remind of us of the project they worked on 10 years ago that was a success. Or they let a temporary defeat turn into a permanent one. They are anchored to the past and it prevents them from seeing the future.
Learn from the past but don’t hang on to it. Yesterday is irrelevant.
