I have to get up at 5:30 so I can get my son up for school. I recently decided to set a habit to sleep at least 6 hours a night but I'm not making it most nights with going to bed coming in around midnight most days.
I'm usually pretty good through the day - no breakfast, lunch at noon, granola bar mid afternoon, dinner around 7.
What I do find though is on days when I sleep in past 8:00 am I'm truly miserable and not fun to be around. What I've come to realize it that it's because I feel I've wasted the best hours of the day - I could have been achieving something.
