When my environment allows me to get quiet time earlier in the evening, I can naturally shift. All the more so if the morning also offers quiet time to myself.

When my environment allows me to get quiet time earlier in the evening, I can naturally shift. All the more so if the morning also offers quiet time to myself. If my evening is noisy, I end up waiting until it quiets down to "unwind"; I find I typically need a couple of hours of peace and quiet. The exception would be when busy and particularly positive circumstances have me quite tired at the end of the day, but this is the exception rather than the rule. If my morning kicks off immediately into unpleasant circumstances -- work is fine, but attempting to work despite a bunch of crap is not -- then I find myself staying up later perhaps out of avoidance; I'm not entirely ready to wake up and put myself through that. TL;DR: I love mornings -- when I can face them rested and not full of crap. Work is not crap, but crappy work is crap.
