I work a full time job, train twice a day - sometimes three times so between 4-5 hours daily. Recently started studying so that's about an hour to an hour and a half daily. Between the above and all the small day to day bullshit I go to bed pretty late and try wake up early and end up getting 4-5 hours of sleep a day. Generally feel like shit when I wake up. How the hell do some of you manage to get 8 hours of sleep while building your empire?
