We’ve all probably heard of Mark Zuckerberg’s choice to wear the same outfit every day. Personal preference aside, there is actually a lot of logic to this habit.
Studies have shown that decision fatigue is real. We all have a finite amount of mental energy for making decisions before we start choosing the path of least resistance. By having a routine in place, you remove the need to keep making the same choices every day, especially when they are inconsequential in the grand scheme of things.
Having a routine should not equate to inflexibility. In fact, you should also adjust your routine as your priorities and goals change. If your aim is to get fitter by the end of the year, then you should probably plot in more exercise slots in your routine. If its near crunch time at work, then you might want to optimise the amount of rest you get to ensure you can perform your best.
