Checklists help you stay organised, better prioritise your time and see the “big picture.” They reduce the number of things you must remember, freeing up valuable headspace for the things that really matter. And if someone else needs to fill in for you, they have a step-by-step guide to tell them exactly what they need to do.
A checklist can be as simple or as complicated as it needs to be. Some will only have a handful of tasks on them; others might be pages long. All that matters is that they serve their purpose: making sure everything gets done.
