Unless your job requires you to wear an actual uniform, deciding what to wear to work will take time out of your morning routine every day. Though the gravity of this decision depends on how fashion-conscious you are, every decision we make throughout the day drains a little bit more of our cognitive energy, and will eventually lead to decision fatigue. Avoid this by assigning yourself a work uniform. Steve Jobs was famous for his polo neck and jeans combo, and many other successful business people do the same. If you wear the same thing every day, that’s one less decision you have to make, preserving energy for the many others you will need to make at work.
