It's been suggested we make, on average, 35,000 decisions every single day. They can range from the mundane to the momentous, but the fact of the matter is, this magnitude of choice makes it more difficult to come to a decision that we're actually happy with. After all, when there are endless options out there, how do you know you're not missing out on something better?
To break the constant cycle of FOMO, try to create situations that limit your need to make less important decisions. For example, settle on three meals you can eat on rotation for a week and batch cook them, so you don't have to think about what to cook and shop for every night of the week. Or cull your work wardrobe to capsule-size to save time deliberating over what to wear in the morning.
