My understanding of the Copper Picking-up principles

Recently I have learned some ideas from Caitong, a well-known author in the most popular Q&A community—Zhihu. Now I want to express his idea with my own understanding in English. By doing this, I could have a more profound perspective about the idea, and at the same time, I could share this brightening idea with more people.
The author’s name, Caitong(采铜), means “picking up copper” in Chinese, and this is also the name of his idea—Copper Picking-Up principles. These principles are used to help people decide what to do in their spare time, which suits me just fine perfectly. According to Caitong, when making a decision about what to do, we need to take two factors into account—how much return we can get(mentally, physically, etc.) and how long the return can last (the duration). With these two factors, we can devide divide things into four quadrants.
Quadrant 1--High Return& Long Duration: Obtaining an effective thinking pattern; traveling; communicating with the top person in your field…
Quadrant 2--High Return& Short Duration: Buy fashionable clothes; playing video games; dinning dining out…
Quadrant 3--Low Return& Short Duration: Surfing the Internet without aim; Wechat messaging…
Quadrant 4--Low Return& Long Duration: Memorising ten English words; reading a classic novel; reply your friend’s email seriously…
If you have a look at your own life, very likely you will find that you spend most of your time in Quadrant Two—High Return and Short Duration, and then Quadrant Three—Low Return and Short Duration. The problem is that the duration of these things are so short that we get bored again, which leads us to a circle where we will find that every day we spend is homogeneous. But for the rest other two quadrants, no matter whether the return is high are not, it can be accumulated day by day, thus a difference will be there if we stick to these things for enough long. For example, assume that you are waiting in the queue, you could either play with your phone or try to remember ten English words. By playing the phone, no difference is made. But if you memorise words and do that every day, you will make a difference. The point is that when we do something which can benefit us in a long term, we are more likely to improve our life. It’s just like picking up copper in a mine, no matter how big the copper is, as long as it’s copper, just pick it up, for once it is collected, it can be worth a lot.

Moving to Seoul

Tomorrow, well practically today since it's after midnight; I am moving to Seoul, the capital city of South Korea.
It is 1:30AM right now and I haven't even started packing. I have just been stress-eating and reading webcomics all day long.
Yes, I am procrastinating the heck out of this. Yes, the chances are that I probably won't be able to sleep tonight.
But why? What is the reason that I can't help being like this? I realised, it's because of the fear. The fear of what?

Technically this isn't the first time I am moving out of home, but back then I was a minor (therefore on my parents' financial support) and it was to study there. I'd say it's quite different this time, as I really am moving out on my own. without a job, when I am basically broke.
That's where the fear is coming from. I am broke and I am moving to a city where cost of living is 6.88% higher than in United States (aggregate data for all cities)*. Why? Because I got this wonderful weekend internship that I was dying to get, which actually doesn't pay anything and isn't really directly related to any money-making jobs out there. But then again, I know for sure that I will learn so much from it, and that I just really want to do it.
so.. yea. the fear is coming from following what I want without an actual and "realistic" financial plan. you know, when you knew that something was what you wanted and you go for it so bravely and then right before you actually dive into it, you kind of get... anxious and nervous and get plagued with self-doubt and then you start questioning yourself, "can you really do this? I mean REALLY?". so I started writing. as writing down your thoughts and feelings always help you organize your thoughts and make you feel better. and now I do feel a lot better as my thought process changed from "I hate myself and I am freaking pathetic" to "I have realized that the reason why I have been procrastinating all day and been very lazy was because of the fear of not having any money in a month and not being able to pay the rent next month. and having to starve. so basically was just worrying about my terrible financial situation. but then again, just sitting here and worrying about it won't fix anything. but actually starting packing and trying to get some rest will do. at least then I will have more energy to get situated ASAP once I get there so that I can look for a part time job ASAP.
so... yea. that is what I'll do now!

A trip to a nature park

Today, I took my family to go to a nature park, which is the largest park in my city. It is an 4A level park, but the important thing is it is free to visit.
We arrived at about noon, when the sun was the highest in the sky. It was very hot. We bought some ice cream at the gate. Then we rented a three-person bicycle. It was a very funny. It was not a bicycle that is ridden by two people in tandem, but it was a bicycle which we can ride side by side, just like we were driving a car. This bicycle was not free, we needed pay 50 yuan for two hours riding and leave 150 yuan as a deposit. That was not too expensive, we can afford it.
In that two hours, we went around the park. I saw the central lake, the zoo, and the flowers of an exhibition, in addition to these, there were a lot of recreation facilities in the park. There were a lot of kids playing in the park, who of course were accompanied by their parents. They played so happily. We were happy too. 

But....The only fly in the ointment is that I got a cold.... 

But the only downside was that I got a cold.

Could you help me please?

Hi there,

Would you please help me with a few questions?

1) In an article, I came across this: When you deal with massive bodies like the Earth, however, which has a mass of 6E+24 kilograms...".. Why is there an article "the" before Earth?

It isn't necessary but you can include 'the'.

2) On a tv show, a man says: "You happen to see my hot wife around?" ... then a woman replies: "No, I haven't".. why "I haven't ? Why "have"?

You are saying 'no' and backing this up with 'I have not' (haven't). Therefore it is not a double negative, and is saying 'have not', rather tan 'have'.

3) Let's say you kind of curse at your friend but silently, just muttering a few words(can I say mutter here?)(YES YOU CAN!) What about curse at someone silently???) , but your friend ends up hearing you and he says: "I heard that."
Would it sound odd to say "Good. You were supposed to" or "Good. That was the intention"? what could I say?

Either would be fine. 'Good, you were supposed to' would be most appropriate.

Please.


Thank you!

"Le Havre" film review

“Le Havre”, which won one prize in Cannes Film Festival in 2011, is a comedy-drama directed by Aki Kaurismaki, a Finish screenwriter and film director. It stars André Wilms, Katie Oudien and Jean-Pierre Leaud, a regular actor of Truffaut's films. The film was set in Le Havre, a french port city from the Normandy region, located on the English Channel.

Marcel Marx, is a shoe shiner, a former bohemian writer who used to live in Paris. He now lives with his wife, Arletty, who suffers from an illness, but her husband is ignorant of gravity. One day, Marcel discovers Idrissa, a young boy that arrived to France in a container, the film shows how Marcel and many of the citizens from Le Havre help the boy by hiding him from the police.

The great strength of this film is the simplicity, it is skilfully acted by the cast and it includes some signs of french culture.

What I like the most is the setting that has a vintage touch, as if the film might have been shot in the seventies. On the other hand, the denouement is highly unlike...or maybe is a message of hope.
