I have a friend who wakes up every day at 2am and works feverishly. He claims he gets his best work done in the wee hours of the night. I do exactly what my friend does except those early morning hours are before I go to bed. In the old days I used to meditate in those hours. I hate my sleep schedule because I wake up late in the day after more than half of the day is over. It makes it hard to do phone calls. But, on the other hand, I do my best work after midnight when the atmosphere is calm and there are no disturbances.
Keep in mind that disturbances include more than phone calls, emails, knocks on your door and noise from outdoors. The atmosphere has other types of interferences that are more meta-physical. When people are awake they create small particles with their thoughts which I call thought-trons. These particles are not formed so much as people sleep. It is more peaceful then because nobody is using their cell phones, lights, or thinking except in their dreams.
So, maybe it is time for a lifestle change. Maybe it is time to stay up later or get up early and do your focused work when others are sleeping. Want to be #1? You have to be different and excel where others fail, be awake while others are sleeping, and be alert while others are checking their text messages!
