Most rushed mornings start the evening before. A bag that is not packed, keys that are somewhere, a shirt that still needs ironing. Ten minutes after dinner can take all of that off the morning.
Pick one spot near the door and put everything you need there: bag, keys, the letter you keep meaning to post. If you take lunch with you, make it now and leave a note on the fridge so you do not walk past it.
Lay out clothes for the weather you expect. Check the forecast once, decide, and stop thinking about it.
The point is not to be perfectly organised. It is to make the first half hour of the day about the day itself, not about searching for things.
