A useful hack I've discovered is to prepare and pre-plan the following day the night before. Review your schedule and jot down a simple to-do list; it helps to visually map out the key tasks and their sequence. You can also prepare everything that you'll need for the following day, such as setting up your work station with stationery and gadgets or laying out clothes and packed meals/snacks.
It's an efficient way to start the day with a clear focus and saves time and energy in the morning when time is often precious. Also, this method ensures you don't embark on a task only to realize you're missing an essential element! It gives a nice sense of control and sets a productive tone from the get-go.
