oman thinking 6 ways to make a decision

Ever find yourself trapped in a whirlpool of choices, only to make decisions that leave you questioning your judgment? This is the silent predator known as decision fatigue. It's the stealthy consequence of an endless barrage of decisions, leading to a decline in both the quality of our choices and our mental stamina. This relentless cycle not only wreaks havoc on your productivity but also nibbles away at your overall well-being. But fear not, we're about to embark on a journey to conquer this invisible adversary. Unveiling six powerful strategies, this blog post aims to help you overcome decision fatigue and catapult your productivity to unprecedented levels.

1. Automating Your Daily Routine to Prevent Energy Drain

Automating your routine can save your mental power, from picking clothes to deciding which task to start with, thinking about what to tackle after waking up can drain your energy. So, you can transform your morning routine into a structured work routine and follow its schedule to save your mental energy.

For example, establish a morning routine, from waking up to going to work. Taking multiple actions in quick succession depletes our energy. Once you get used to it, you'll smoothly transition from one task to the next without wasting time or energy pondering what to do next.

2. Reducing Actions to Save Your Mental Energy

As mentioned earlier, engaging in numerous activities throughout the day can lead to mental fatigue. Do you constantly check messenger apps or social media during your free time? Do you frequently switch between tasks? These actions contribute to decision fatigue.

Imagine this: you start the day with 100% of your mental energy, and every time you perform a small task like checking your phone or thinking about dinner, it depletes 1% of your energy. In contrast, a significant job like your work consumes 10% of your energy every hour. By the end of the day, you might run out of enough mental energy when you need to make important decisions. Strive to minimize unnecessary actions to save your mental energy for making decisions that matter.

For example, set specific times to check emails, say once every few hours rather than every few minutes. This systematization of your routine can save you from energy depletion caused by quick, successive actions.

3. Making Important Decisions Early in the Day

Our mental energy tends to peak in the morning and gradually declines throughout the day due to work, physical activities, and other mentally taxing tasks. Consequently, making crucial decisions later in the day may not yield optimal results. Therefore, it's best to make your important decisions early in the day.

4. Concentrate on One Task at a Time

We often find ourselves surrounded by numerous tasks and feel the need to complete them all. However, spreading mental energy into multiple activities can lead to decision fatigue. To conserve your mental energy, focus on one task at a time.

Comparing focused energy on one task vs. multitasking

To illustrate, consider your workload. Are all the tasks equally important? If not, eliminate less impactful tasks. Also, implementing the 80/20 rule can be helpful:

80 percent of results come from 20 percent of effort and work

If it seems like everything is important and you're unsure which one is crucial, try temporarily removing a task for a week. It might be an obstacle rather than a necessity if it doesn't significantly affect your life or work results. If you determine that's an important task and want to optimize your productivity, consider outsourcing it.

5. Get Full Night Sleep to Enhance Decision-Making Power

Sleep deprivation can negatively impact productivity, problem-solving skills, Decision-making, and so on. Consistently getting less than 6 or 7 hours of sleep can impair your decision-making ability and increase the risk of making significant errors.

A full night's sleep can enhance your decision-making skills. Aiming for 8 hours of sleep per day can optimize your decision-making abilities, prevent decision fatigue, and maintain your overall health.

6. Having the Right Diet to Feed Your Brain and Fuel Your Decisions

Omega-3 fatty acids can boost brain function and potentially reduce decision fatigue. Omega-3 fatty acids are found in foods like fatty fish (e.g., salmon, mackerel), walnuts, and chia seeds.

We often crave sweets and reach for coffee to recharge energy especially when we're tired. Sugar provides a quick energy boost but should be avoided to prevent brain fatigue and maintain overall health. Consuming highly processed sugary foods without protein, fiber, or healthy fats can cause rapid spikes in blood sugar and insulin levels, leading to a short-term energy increase followed by increased fatigue within 30 minutes.

Similarly, excessive caffeine can initially boost alertness but can lead to increased fatigue as its effects wear off. A proper diet is crucial to boosting brain function and preventing decision fatigue.


Decision fatigue can stem from various sources, including an overload of tasks, inadequate sleep, and poor dietary choices. Focusing on critical tasks, prioritizing adequate sleep, and maintaining a balanced diet can help conserve mental energy for better decision-making. By adopting these strategies, you can effectively manage decision fatigue, enhance your productivity, and improve your overall well-being.
