I am aware we cannot live in the past, nor can we return and change it. If we all 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 learn from the successes and failures.
2) We plan a better future based on history.
3) We establish measures to prevent duplicating mistakes.
4) We lead others on a straighter course.
I know we all strive to survive the present with an anticipation of the future. However, we also need to stop occasionally and benefit from the past.
