About
Mideum-ui Geim, Silhaeng ("The Game of Belief, Action") translates complex brain science into plain language — and into habits you can put into practice in everyday life.
Why this site exists
Everyone wants to build better habits. Advice like "how to become a morning person" or "dopamine detox" is everywhere, but few articles explain where that advice comes from, or whether it really works the same way in your own brain.
This site was made to fill that gap. The goal is to put what brain research actually says into plain words, and to turn that knowledge into small actions you can take today. In the site's name, "the game of belief" stands for the belief that change is possible, and "action" for the repetition that turns that belief into reality.
What we cover
Every article sits on the timeline of a day. We mark the moment when a habit actually happens — morning light, an after-work walk, the time you go to bed — so you can picture right away when to put what you read into practice. Topics that aren't tied to a time of day are marked "Anytime."

Our content principles
Our editorial philosophy fits in one sentence: explain complex brain science simply, and offer fact-based information you can actually use. To do that, we follow these principles.
- We cite our sources. We rely first on peer-reviewed research and official guidance from professional societies and public institutions, and every article ends with its references.
- We say only as much as the research does. We don't apply animal findings directly to people, and we don't present correlation as causation. We note who was studied and the limits of each study.
- We don't exaggerate. You won't find phrases like "hack your brain" or "change overnight" here. Habits usually change slowly, and we say so honestly.
- We end with action. Every article closes with "Today's practice": concrete steps you can try right away.
- We correct mistakes. When we find an error or more accurate research appears, we update the article. Error reports are always welcome.
