+
+This book teaches me what a real _rational_ person is like:
+
+- Those who keeps their superego in whatever emotional, situational, or environmental state
+- Those who can stand on the psychology of losing their precious ownership on something they value and keep moving on
+- [Those who live by principles and not by feelings](https://trello.com/c/AvupcAv4) (which is why people ought to 
+  study Philosophy, History, and Science to train the skill of being rational)
+
+In addition, the author's "extra" curiosity is what opens up the world of human's irrationalities. A tiny detail in life
+ignorable by almost anyone is often picked up by Dan as the starting point of a rather astonishing discovery about
+irrationality of minds. Surely, human's irrational world has just been explored by just a less than 1% in this book.
+What should be taken away, in addition, is the methodoloy Dan employed:
+
+1. Start from live events
+2. Ask questions
+3. Conduct scientific research (or, for us, searching oneline materials for answers)
+4. Make conclusion
+5. Make induction

 - Although almost everyone has problems with procrastination, those who recognize and admit their weakness are in a 
   better position to utilize available tools for precommitment and by doing so, help themselves overcome it.
 
+Ch. 7 - The Irrationality of Ownership
+--------------------------------------
+
+- While selling something, we focus on what we may lose (the things to be sold), rather than what we may gain (the 
+  money which we can use to purchase something else new)
+- Buyers do not share the same experience & feeling with Sellers toward an object and thus sees different prices between
+  them
+- What we mean by "ownership" _irratioanlly_?
+
+  - The more work you put into something, the more ownership you begin to feel for it.
+  - The pride of ownership is proportional to the difficulty of making it happen
+  - Once they thought of themselves as owners, they were compelled to prevent losing their position by bidding higher 
+    and higher. Examples include
+
+    - Virtual ownership
+    - Product trial
+
+  - The consequence of injecting a sense of ownership into one's mind is that _we love it perhaps more than we should. 
+    We prize it more than it is worth. And most frequently, we have trouble letting go of it because we can't stand 
+    the idea of its loss. What are we left with then? An ideology—rigid and unyielding_. This tactic has been exploited
+    a lot in business world - They make it hard for you to gain; and once you own it, you keep paying to keep it (e.
+    g. gaming)

+- People are beset not by a lack of opportunity, but by a dizzying abundance of it. People today are continually 
+  reminded that we can do anything and be anything we want to be. We spread ourselves too much.
