1: Pack you briefcase and tote the night before. While you're there, make sure to clear out any clutter, such as old receipts, tissues, loose change.
2: In the evening, lay out your clothes you will wear the following day (I do this every night), right down the corresponding accessories, so you are not pulling out the contents of your lingerie drawer to search for the right shade of tights in the morning rush. I know a chic working woman who keeps her stockings in separate bags according to color so she's not trying to figure out which is blue and which is black in the dim morning light. This would come in handy if you forgot to lay your clothes out the night before.
3: Plan what you are going to have for breakfast the night before and set out any necessary ingredients (keep the refrigerated food together, set dry ingredients on the counter-top). Blend your morning smoothie drink and keep it in the fridge ready for the next morning. Set the timer on your coffee machine so you awaken to the fresh aroma of your favorite brew.
4: I still advocate sitting down to eat breakfast, but on those mornings which you are running late for the train, you can always put that smoothie in a to-go cup or thermos.
5: If you are taking the kids to day care on the way to work, make sure everything is packed. Lay out their clothes for the day, keep the sunscreen accessible, and pack any snacks and water bottles that might be needed, Keep this all by the front door so you don't forget anything.
