Jealous?!?!

In my country they have an idiom like this " if you look up to someone better than you, you will feel worse but if you look down on someone more worse than you, you will feel better".
In this life, nobody is the same. We are unique but sometimes we compare ourselves with others, even our relatives or best friends. At school, you would be sad if your best friend got bad scores but you would also have more sadness if your best friend had a better score than you. If someone just moved to a bigger house and told you, you would want a bigger house than they have. When they have something, you will always want a better one. Yes, sometimes it is good because it makes you try to be better but sometimes it's not. When we are jealous with somebody, we focus our energy on that and we can't do anything. We always follow them and see what they do and what they have. The worst thing is we feel bad about ourselves (or you can say 'we have bad feelings about ourselves'). we lose  confidence. How can we improve it? In my opinion, the best way to improve is to pay attention to ourselves. We make a plan or goal  to makes our life better. When we complete it, we will feel good and at that time we realize feeling good inside is better than comparing ourselves with others. I think the idiom at the beginning is a little bit wrong. we don't need look up or look down on someone else. Just be yourself. Let's compare yourself at this moment with that past and future. That's all.
p/s: that is all my experience and my opinion :) :)

- the word 'wanna' can be used in informal speech to say 'want to' but not 'want a'. Still a good job and if you have questions feel free to ask :)

English

English is an common language used widely in many Western countries and also Asian countries as a second one. Learning this language helps us a lot by not only in allowing us to adapting to an international working environment but also in communicating with people all over the world. Because of its importance, as English teachers , they need to be dedicated to their students and inspire them so that they can love discovering much many more things than textbooks or boring listening materials taught in school in order to fill the gap in their language database . Personally, I don't appreciate the way Vietnamese teachers teach English learners. They only focus on grammar rules, and how to recognize tenses in a wrong way. Students are trained to do English assignments but not to use it in real life. That's why there is a number of Vietnamese students who are not able to speak English on regular basis. Most of my friends consider it a frustrating subject, not because they do not want to learn, but because they are put under pressure of getting high marks or passing through class, which makes learning language become more and more difficult. When it doesn't come from the desire, it has no meanings anymore. Therefore, like I mentioned before, teachers play an important role as well as have a big influence on the nation's younger generation. If any Vietnamese English teachers are going to be reading this notebook, I hope they will think about this problem more and figure out a new method for a new dawn of learning. This is my only concern as an language learner.

That's it for today. Hope to be corrected mistakes have my mistakes corrected :)). Thank you so much for reading !

-great job! if you have any questions about corrections feel free to ask
