If you read about Mussolini or Stalin or some of these other great monsters of history they were at it all the time that they were getting up in the morning very early. They were physically very active. They didn't eat lunch.
I tell you the past is a bucket of ashes so live not in your yesterdays no just for tomorrow but in the here and now. Keep moving and forget the post mortems and remember no one can get the jump on the future.
