Symbioseis

Symbiosis is a bit scientific. You usually hear about it in biology textbooks.

Thus the third topic of my notes will be symbioseis.

"Thus" is a connector. You can't use it as a first sentence in the essay. You need a sentence before that so "thus" logically connects to the sentence before it.

I think I have athe best friend ever.

Today he share with me hisd his career achievements in jobwith me.

He got an offer ifrom an IT Company (called) "Kefir".

I'm was very glad to hear that, because thats was our purpose, and I'mgoal, and yet I felt a little sad with that.

"Purpose" is something more general, while "goal" is something specific and measurable. For example, the purpose of a car is transportation but the goal of using a car is to go to a specific place.
So, goal works better here.

B(I was sad because) I just started compare me withyself to him.

But I thought about it.to myself OR I wondered:

"Why do I compared me withyself to him?

Why did I started to envy him for his success?"

BIs it because I don''m not satisfy myied with my own life?

OK,I asked myself what I wanted to change? and what he has now that I don't.

What he has right now after that, which I don't have?/

Merged the two sentences together.

And I understand, I need this man, because he justThen I realized: I need this man in my life. He showed to me a simple and very important thing, which i understand right nowsomething simple yet vital.

Just iImagine this, if you have got paralyse, and what do havebecame paralyzed. What would you have left at that moment?

OK, but what do you have at the end of your life?/

Only the thoughts, and memories of when you compared yourself with somebody else.

After when that sentencethought appeared in miy mind, I madereached a conclusion:

"make a conclusion" sounds a bit unnatural. You reach a conclusion - you don't make it.

The mainost important thing in my life it'ss to remember myselfwho I am, rather than remembering yourself when you compared yourselfwho I was in comparison to someone else....

I call my friend as faster as I canould, and told him aboutwhat was on my minds and give him a congratscongratulate him for his success.

And after my speech part, he told me about same thinghe had felt the same way before.

He just gotexperienced this a little earlier.

Wwhen I went to the Japan ese Embassy forto take exams ofor the education grant.

And he gotHe had the same feelings, but he madecame to a different conclusion.

You "come to a conclusion", you don't make a conclusion.

He looked at me, which - someone who tried to "catch the tail of fortune and" by passing the exams with very ludicrousittle preparation xD.

"Ludicrous" means something like crazy or unreasonable.
It could work if you had used it as "with a ludicrously small amount of preparation" for example. But "very little preparation" works just fine!

I prepared very bad, even didn'thadn't even learned Japanese xDyet!

He told me this thing:

"Why I should I envy me, ifyou, when I should be congrats him, if Iulating you as a friend.

You should put the entire monologue under quotation marks (" and ").

He go on my road, I go with him on our own roadYou are on your path, and I am on mine, but we walk together.

"Road" refers specifically to a road you would see in real life. When speaking a bit more philosophically and metaphorically, use "path".

And we as friends have to help to each other.

Envy like a poison, - whenever you have goget this felleling, you should to movehrow it itn tohe trash.

You "throw something in the trash".

A few days after your trip to embassy, I forgot about my envy, and startinged to understand, that your trip to the embassy showed me wthat I shouldneeded to be more patient with my other purpose, and startgoals and focusing on main thingsthe important things in life.

Goals is better that purpose.

Also, "main" means something like the most common or central part of something - it refers to the central part of something that has multiple parts. In this case, I think you meant "important", so use that instead.

After that, I prioritized my goals and after half a year I'velater, I got an offer. xD

Wow, congrats!

Symbioseis

We are like a creatures (which receivinge a benefit after our) benefit after each other's success.

Sometimes, a simpler way of saying something is superior. "Which receive a benefit" is very stiff and a bit unnatural. It's much better to just use the verb "to benefit" - simple, but totally natural.

I have athe best friend ever, and I'm very happy to have you.
