In a society demanding constant focus, we often criticize ourselves for momentarily "losing touch" with the present. However, psychologists suggest these seemingly strange behaviors indicate the brain is engaged in complex, flexible thought processes.

Daydreaming

Many consider mind-wandering a lack of discipline. However, recent studies show it serves as an "exercise" for creative thinking.

A 2025 study involving 1,300 participants revealed that individuals who actively allow themselves to daydream often exhibit higher problem-solving performance. During these periods, the brain strongly connects its control and imagination networks.

Instead of being confined by monotonous realities, their brains connect disparate data to generate breakthrough ideas. This ability to temporarily "disconnect" from reality signifies a flexible intellect constantly seeking new solutions.

Talking to oneself

Muttering plans or speaking softly while working might seem unusual to others. Science, however, refers to this as a tool of metacognition – thinking about one's own thoughts.

According to a 2023 study in Behavioral Science journal, self-dialogue acts as a "cognitive framework", helping to systematize thinking, transform abstract concepts into concrete action steps, and enable the brain to regulate emotions and focus on goals amidst distractions.

In other words, intelligent individuals often use inner speech to "untangle" their brains, bringing order and logic to chaotic thoughts.

While these habits are signs of intelligence, they are only truly effective when mastered. To transform these "annoyances" into "advantages", American psychologist Dr. Mark Travers suggests:

Conscious daydreaming: Allow yourself 10-15 minutes of rest after stressful work hours for your brain to freely associate. This is often when breakthrough ideas emerge.

Self-guidance: When facing a difficult problem, try to articulate it as if explaining it to someone else. This helps you see the problem more clearly.

Balance with reality: These habits only unleash their power when combined with high self-awareness. Do not let wandering lead you too far from important goals.
