There’s a trope in movies that we could all use: The learning montage. You lack a skill. You need to prepare. You are working for a goal. No one wants to watch anything resembling a realtime series of growth or progress, so the montage is utilized.
We all wish we had the montage in life. It shows all that growth and progress without all the slow drudgery of work. For every rabbi, a montage of high holiday prep would likely show clips of surfing the web, folding laundry, pulling books off of shelves, some staring into space, and then a shot of inspiration and a couple quick images of typing furiously before standing on the pulpit in triumph. Writing isn’t as compelling as training to fight to Apollo Creed.
