I am torn. I like sleeping in, but I also enjoy waking up early and having a full day. Mornings are peaceful, but also boring so that is another reason to sleep in.
I go back and forth. I don't make appts till after 10am.
When recently ask to come in at 8:30am I asked "why? feel like pushing your luck?" At that early Im either going to be VERY irritable and tired, or too sleepy to care.
