You wonder how nobody noticed how much of a total CF everything had become long before the actual event.
Realizing you are in the early stages of a CF, especially as a newcomer in training, is the challenge.
When I was in a very early stage of Navy flight training, some wise instructor said to me once: when you're at the end of the runway feeling rushed to get through your takeoff checklist, and the tower says "cleared for immediate takeoff" or "if you can expedite, you are cleared for immediate takeoff", the answer is "unable", set the parking brake, take 5 deep breaths, and start the checklist over.
