In my own experience, I believe people have been trained from a very young age to "get up and GO" and for many years working in Software I would wake up and immediately start thinking about work problems etc.

My conclusion is that it is a waste of mental energy which is very evident on days you are feeling under the weather etc. These days it is all about a gradual wake up, having a nutritious breakfast and spending time with my dog (walking) before I leave for work commute.
