Notice your decision fatigue.
There is power in naming what is going on and in not blaming yourself but recognizing that this is a normal reaction to a high demand situation.
Take a break if possible.
Tell people, “I need a minute.” Step away and gain some perspective. Doing a simple task you enjoy – walking, a hobby, playing a game – gives your brain a rest. Taking your attention off the situation can result in solutions rising to the surface as your unconscious mind has a chance to mull things over.
Remember your brain is part of your body.
Your brain is not a separate entity. The basics of sleep, hydration, nutrition, and movement help you feel better and think more clearly. Consider what will help you gain some energy.
Let people know that you need more information or time.
“I am not sure what the long-term outcome is of that. Can you go over it with me again?” “When do you need an answer on that?” Sometimes decisions can wait until you have had time to rest or learn more.
Postpone decisions that can wait.
Write it down in your calendar so your brain gets the message that it can take a break. If someone needs an answer in 10 days, write a note to yourself to pop up in 7 days so it doesn’t become another emergency.
Automate routine decisions.
Eat the same breakfast, wear the same earrings, go to a familiar restaurant and don’t bother with the menu – order what you know you like. Set up a wardrobe plan and wear your decided upon clothes.
Make broader decisions when possible.
When moving, my friend’s parents took everything they wanted out of the garage then told us “Tools and car books still in the garage can be divided up between the kids. If nobody wants an item put it on the curb on trash day.”
Delegate decisions to someone else.
While setting up for a wedding the bride told her friends, “The flowers are in the church kitchen and there are a bunch of vases on the table. Please decorate the lobby and altar.”
