Don't criticize, condemn or complain. “God himself, sir, doesn't propose to judge man until the end of his days. So why should you and I?” 

I was a highly critical person, often too quick to judge. But after some reading, I realized how foolish I was. Instead of thinking about the negative of everyone, I would like to remind myself to look at their positives and if possible, not to criticize them. I also have been a complainer, saying bluntly to people about my dislikes about them or my circumstances. With the reading in mind, I am no longer a complainer. This lead to some fruitful rewards, people will be less likely to think of me as a negative person, but as a positive person. 

Give honest and sincere appreciation. "Be hearty in your approbation and lavish in your praise. "

I seldom give approbation and praise to people before, but after a few tries, I am convinced that it has made people like me more. This could be a double-edged sword though, hence the keyword sincere needs to always be in mind when giving out praises.  Now I will always try to genuinely appreciate friends and tell them what I like about them. 

Arouse in the other person an eager want.  “If there is any one secret of success, it lies in the ability to get the other person’s point of view and see things from that person’s angle as well as from your own.” “The world is full of people who are grabbing and self-seeking. So the rare individual who unselfishly tries to serve others has an enormous advantage.” 

I became a leader in a group assignment last year before I touched a single page of this book. I failed as a leader, I only have the motivation, but not the required skillset to handle people. After reading this chapter, I studied my mistakes and pondered on how could I do differently. A groupmate underperforming isn't his fault, it was entirely mine for not arousing an eager want. I should have gotten his perspective on what he wants, then aligned his want with mine. I should have been less selfish and tried to serve people instead of expecting them to serve me. 

Become genuinely interested in other people. “You can make more friends in two months by being interested in other people than you can in two years by trying to get other people interested in you.” 

This is a hard lesson I had to learn. I did not have many friends back then, and my mindset was wrong - instead of being interested, I was not interested in people if we do not have the same interests. Thankfully after reading this chapter, the social animal in me has awakened. I tried to implement this technique when I went to Japan for a global exchange program and I found out,  lo and behold, my friendship scheme worked! I gained more friends during a 14-day excursion than I did during the entirety of my high school years. 

Smile. "A man without a smiling face must not open a shop."

In an increasingly selfish and cold world, I find looking at a person's smile can give a blissful sense of coziness. As a customer in a shop, I will instantly like the service staff when they smile. After reading the chapter, I tried applying simple changes such as smiling when meeting others or just walking down the street—not only did people smile back more often, I felt better too. Furthermore, I set up a reminder on my phone to notify me to smile at 3 PM every day. This will alert me in the hours after lunch when I usually feel sleepy and my mood has dimmed. Another technique I could use is the "accountability mirror" which David Goggins used and wrote about in his book Can't Hurt Me. I put post-it notes on my mirror and wrote SMILE on it, and every day when I look into the mirror I will read it and be reminded to smile.

Remember that a person’s name is to that person the sweetest and most important sound in any language. "The average person is more interested in his or her own name than in all the other names on Earth put together."

I had always thought remembering people's names is a natural talent for me, but the more I dive into the skill tree of my life, I found out it was caused by my obsession with watching sports and playing sports video games. Take football (soccer for Americans) for example, there are 22 players playing on a single pitch, and if I as a kid actively learn the players' names, my brain will be wired to easily recall names. I dissected the ways I remember the name and one of them is by association - where I link a particular aspect of the person to their name. For example, when I want to remember David Silva from the Spanish team and Man City, I researched his unusual ethnicity and found out he is half Spanish half Japanese - this helped me connect the dots when I see his mixed-race face. What happens if I just met a bunch of strangers at a dinner table? Another technique I try to use is repetition in conversation, which I learned in this book, and is the act of actively saying a person's name in a talk. This reinforces the notion that I remember their names, but also aids me in planting their name into my library of human names. 

Be a good listener.
