I live like this, although not to the extreme as discussed in the article. I have my alarm set to go off at 3AM, also called the 'Witching Hour'[0]. It's when I'm most creative, and all the sages used this special time to write, paint, etc. I've come to gradually learn this is the optimal time for coding & writing. My physiology is wired a certain way, and it's great the way there's no interruptions by family members, friends, or traffic. It's the time to Get Sh*t Done.
