We cannot live in the past, nor can we return to change it. If we had a chance to live yesterday over I am sure there are areas we would change.
Yesterday provides a benefit to our leadership in several ways.
1) We can learn from the successes and failures.
2) We can plan a better future based on the history.
3) We can establish measures to prevent duplicating mistakes.
4) We can lead others onto a straighter course.
I know we all strive to survive the present with an anticipation of the future. However, we also need to stop on occasion and benefit from the past.
