I've always found getting up early to be far more productive, but as you say it could just be me. I work in construction so getting up early is part and parcel of the job but ive found even on my holidays and weekends now i prefer to get up early, say 5 am and get things done, if im feeling sleepy around lunchtime ill have a nap. I really shouldn't comment too much on sleep cycles as i only sleep 4-5 hours a night, i prefer to spend my time while im young conscious even if it kills me a little earlier :)

nice post upvoted
