I sleep about 6 hours a day, when work needs to be done maybe 2-3 hours throughout the day by doing power naps.
Oh my god. You are just like machines. I suggest you care more about your health which is more important than work and money. I sleep at least 7 hours a day.
8 hours. Can do 7 though, even 6. I'll only do 9+ if I have a bad sleep the night before. 8 is about what I get if I'm consistent and not disturbed.
I usually try to get eight hours of sleep. However, I cannot fall back asleep after I awaken. My mind instantly wants to jump on the computer.
