3,000 kilometres from home and still came out of the week feeling satisfied with the effort. That's the harder version of productive. It's easier to perform well in a familiar environment where everything is set up the way you like it.
The question you asked at the end is the one I keep thinking about. Weekend recharging only works if you actually stop. A lot of people rest in theory but keep one thread of work tension running the whole time. By Sunday night they're not actually rested, just stationary.
Hope you managed to properly switch off.
