What will today bring?

What will today bring? Should we look at yesterday to determine how today should go? A lot of the uppers at work keep stressing that what happened yesterday is done and let's push for today. I agree with that to a point.

We should look at what happened yesterday to see how we can improve or keep up what happened. We should use yesterday like we use history, to learn from it. Keep a notebook that tracks your success and failures. Write them down. Always be learning from them.
