Delete That Person from Your Brain

A science-informed guide to evicting the person who lives rent-free in your head – once and for all

Why is it so hard to stop thinking about difficult people?

The answer lies deep within our brain’s survival instinct. When someone triggers anxiety, anger, or fear, our mind automatically marks them as a "threat"—making it nearly impossible to simply ignore them.

This book offers a revolutionary solution: don’t fight your brain’s wiring—retrain it.

Rather than asking who "deserves" space in your mind, this practical guide teaches you how to erase the mental presence of problematic people and reclaim your attention. Through simple techniques and real-life examples, readers learn to shift their brain’s focus away from negative emotions and toward what truly matters: personal growth, creativity, and happiness.

The result is a lasting transformation—not just a temporary relief.
When the mind is no longer occupied by "that person” – whether it’s an ex, a problem friend, a challenging family member, or a former boss or colleague who seems to have a hold on you, long after the fact -- it finally has space to grow stronger, freer, and more fulfilled.

Delete That Person from Your Mind is a refreshing, empowering book for anyone who wants to move beyond resentment and anxiety toward true freedom.Michihito Sugawara is a practicing neurosurgeon living and working in Tokyo, Japan.
