flow (and manage your energy)
Flow, a state of concentration or complete absorption with the activity at hand and the situation. (from Flow: The Psychology of Optimal Experience, by Mihaly Csíkszentmihályi ) [http://en.wikipedia.org/wiki/Mihaly_Csikszentmihalyi]
..and try to combine that concept with The Project Energy by Tony Schwartz (http://www.theenergyproject.com)
Now, to cut to the chase, I am much more productive in the wee hours or an hour or two before the wee hours. That is when the state of ‘flow’ kicks in to write or ‘pour my thought into words and sentences’.
We all need to find that time or place when we are in the state of ‘flow’. Or manage our energy well by simply having enough sleep, nourishment and exercise. Easier said (or written) than done, I know..
In the final analysis, be in the ‘flow’ or ‘manage’ your energy well and be productive.
