Stop overthinking and start doing

We often mistake rumination for cautious, high-level problem solving, but it is actually a biological "safety system" misfiring. While we believe we are being responsible by analyzing every variable, we are actually hitting a cognitive bandwidth limit known as Miller’s Law, which states the working memory can only hold four to seven chunks of information at once. When we exceed this limit, the prefrontal cortex shuts down and hands control to the amygdala, shifting our state from logical planning to a "freeze" response that views decision-making as a mortal threat.

The 70% Rule is a strategy used by leaders like Jeff Bezos to combat the "Perfect Information Fallacy," which is the false belief that one more data point will eventually eliminate all uncertainty. The rule suggests that most decisions should be made once you have gathered about 70% of the information you wish you had. Waiting for 90% or more usually results in being too slow, as the extra time spent researching provides diminishing returns while the world and market continue to change around you.

Maximizers are individuals who refuse to make a choice until they are certain they have found the absolute best possible option, often leading to increased regret and anxiety because they remain aware of all the alternatives they "lost." In contrast, Satisficers set clear criteria for what is "good enough" and commit to the first option that meets those requirements. Research shows that while Maximizers might occasionally get better objective results, Satisficers are significantly happier and less prone to depression because they free up cognitive bandwidth and avoid dwelling on paths not taken.

A "two-way door" decision is a reversible action, such as testing a new website feature or trying a new hobby, where the cost of failure is low and you can easily pivot back to your original state. A "one-way door" is a high-stakes, irreversible decision that requires more careful deliberation. Most daily anxieties stem from treating two-way doors as if they are made of reinforced steel; recognizing that a decision is reversible allows for a "bias to action," where you prioritize moving fast and learning through doing.

Choosing not to act is not a neutral or safe choice; it is a "sacrifice of momentum" that incurs an opportunity cost. Biologically, chronic indecision keeps the body in a state of persistent low-level stress, marinating the brain in cortisol. Over time, this stress hormone can physically degrade the prefrontal cortex and strengthen the amygdala, making "freeze" the default response to future challenges. Professionally, waiting to act prevents the compounding interest of learning, meaning you lose out on the expertise that comes from small, iterative failures.
