I agree, there are a ton of things out there and they love to tell us what to do! I just follow my body, sometimes if I'm doing reports at home I will wear shorts and a t-shirt, but most of the time I dress as if I'm about to walk out the door. That subconsciously tells me, "I'm leaving soon, so get the reports done!" Sometimes I'll make coffee at home (Arabian whole bean from Amora) or I'll go out and get one, then come back home to work.
In the morning it helps when I jump out of bed and pretend I'm late. After my morning shower routine I'll take a step out on my balcony; take in the morning sky, listen to the city wake up, and hear the early morning traffic.
