There's a song in the classic musical called "My Time of Day". In the song the character, Sky Masterson, sings about his favorite time of day. I have the same favorite time of day, but I get there from the other direction. Sky stays up all night, and enjoys the stillness and beauty of the early morning before everyone wakes up to start their day. I also enjoy that time, but I go to bed early and wake up to enjoy the silence before the world wakes up. It is a beautiful time of the day, and it's easier to be productive and focus on your personal goals when there aren't other people or things to occupy your time.
