Never start work first thing in the morning.
Editors much prefer a terrific rush in the late afternoon.
Please smoke in the editing suites. It assists concentration. Do not arrive with a clear concise plan of what you have shot or indeed what the finished item is about. It does spoil the element of surprise for the editor. Please dash into editing, utter a number of incomprehensible thoughts on how you think the item should be cut and then dash somewhere secret where you cannot be found.
