Psychiatrist's 3-Step Rule of Three to Beat Decision Fatigue & Make Better Choices (2026)

Decision fatigue is a common issue that affects us all, from the mundane choices of what to eat for lunch to the more significant decisions about our lives. It's a phenomenon that can easily overwhelm and paralyze us, leading to overthinking and indecision. But there's a simple solution to this problem, and it's called the 'rule of three'.

This approach, developed by Dr. Sue Varma, a board-certified psychiatrist, is a powerful tool to help us make better decisions and reduce decision fatigue. The 'rule of three' is a three-step exercise that can be applied to any decision, big or small.

Step 1: Narrow Your Options to Three

The first step is to limit the number of options you consider. Instead of weighing many choices, focus on the three strongest options. This simplifies the decision-making process and makes it easier for your brain to manage. By narrowing down the options, you transform an overwhelming decision into a manageable one.

Step 2: Give Yourself a Deadline

To prevent overthinking, set a deadline for your decision. This could be three minutes, hours, days, weeks, or months, depending on the nature of the decision. For smaller choices, a shorter timeframe is often sufficient. However, for more significant decisions, like moving to a new city, a longer deadline might be more appropriate. The key is to create a sense of urgency and prevent yourself from getting stuck in a loop of endless deliberation.

Step 3: Limit Outside Opinions to Three Trusted People

While seeking advice from others can be beneficial, too much input can lead to confusion. Instead of consulting a large number of people, limit your sources to three trusted individuals who understand your values and priorities. This ensures that the advice you receive is aligned with your own judgment and helps you make a more confident decision.

Why It Matters

Decision fatigue is a real issue that can impact our lives in numerous ways. It can lead to executive function skills decline, brain fog, procrastination, and overall dissatisfaction. By minimizing decision fatigue, we can improve our ability to make choices based on our values rather than our emotions. This approach encourages us to make decisions that align with our long-term goals and well-being.

How to Get Started

To make the most of the 'rule of three', Dr. Varma suggests a few key tips. First, ensure you are well-rested, as sleep is crucial for effective decision-making. Being less reactive and more calm can significantly impact the quality of your choices. Second, trust your values over your current mood. Discomfort does not always mean you made the wrong choice; it might be a sign that you are making a challenging decision that will ultimately lead to long-term gain.

In conclusion, the 'rule of three' is a simple yet powerful tool to combat decision fatigue and improve our decision-making skills. By following these steps, we can make choices with greater confidence and clarity, leading to a more fulfilling and satisfying life. So, the next time you're faced with a decision, remember the 'rule of three' and give it a try!
