Most of my adult life, I haven't been a “morning person.” If I could sleep late and begin my day slowly, I would. But most of the time I couldn't.
Although I wasn't a morning person, I was (and am) a responsible person, so if school, work, children, or any other pressing situation required I get up early, I would drag myself out of bed and get going. And that was most days.
Now my children are grown, and I work from home, so I can get up and start my day any time I wish. But ironically, I now enjoy getting up early.
