There are a few reasons why you might feel like you always have decision fatigue. Firstly, it may be because you have a job or everyday life that requires you to make a lot of complex or stressful decisions all day, causing a build-up of stress. It may also be caused by having a cluttered or busy home, where you have to think constantly to find objects, decide where they are going to go, or pick out exactly what it is you need. To help alleviate this, it helps to cut back your workload, seek professional help, or for smaller problems, declutter, and find new organizing methods to help reduce decisions at home.
