On: How I got to 200 productive hours a month

[CamelCaseName]

This is called polyphasic sleep. Wikipedia can give you a much better understanding than I can: https://en.m.wikipedia.org/wiki/Polyphasic_sleep

From personal experience when I tried this briefly in high school, I wasn't getting very deep sleep and just kept ending up tired. Perhaps if I had continued I would have adjusted, but I gave up after just one week.
