Sleep is definitely important. I'm not saying it isn't, but everyone's body works differently. For me, my sleep is broken up because my day job is exhausting. So everyone has to do what is best for them. It's just 8 hours is already 1/3 of the day gone. My goal is to also create passive income. The online world is definitely a difficult one to navigate, but well worth it when you can make it work to build the life of your dreams.
