It's always difficult at the start. I takes a lot of time and determination to learn an instrument. But if you catch the fire no amount of work is too much. It's like someone said, you'll spend hours lost your own world even if it is only practice.

My school

I am a student at ETS Rade Koncar. I am at the 3rd grade (I am at level three/?). My school does well at sports such as basketball and volleyball. We have won many competitions. The/Our School is full of gamers who play League of Legends and games like that. Most students play some sports also, like me too. We think that is very bad for them. My school doesn't have girls but there is one I think is pretty.  I am in love ,you know? Her name is Nikolina. The/Our School has only four grades (OK, I see grades=levels) and it's the same like in most european high schools, I think. Our discipline is well known in other schools. They think that we are vandals and animals. Yeah, sounds very bad doesn't it?

Answer to a friend

At First off, I want to tell you that your letter was my English lesson this week. I read, reread, and looked for the meaning of unfamiliar words. I know there are so many articles, reports, magazines on line. But you are right, a private letter has a special value. Surely I learned from you (maybe certainly?). As you know my English is not so good and to express my ideas becomes (takes?) a hard work. So while I can’t reply as you deserve, and I also can’t say thank you enough.

(Good job!)

My first note

It's night. The only thing I want to do now is to go to bed. I am really tired. My homework was a bit is more difficult than last year. It's the same with life I think. When you get older your tasks are getting bigger and more difficult. Well, things are not bad at all. It's new years eve and everybody outside is happy and they want love. I don't need it. Others may think that I am a wierdo but I just want to be alone. Maybe it's not right but it is good. My only wish is that I want to be like Charles Bukowski. He is my idol and I´ve read all his books. I don't know what to write, right now. I didn't thought think about any subject before hand. at this moment. It's only my first note and this is it. Not a big deal. What do you think?

(I changed "wanna" to want to. If you were wanting to use some type of street language then "Do what you "wanna" do!)

about love

I do not understand why God allows us to fall in love. I think that I've never experienced true love. I mean I love my family and love my friends, but when it is about couple love that is more complicated. And this time, as a punishment, I am now alone and love is not reciprocated. There was a time when I could have all I wanted, but this time (now/?) i can't stop thinking about him. I just saw him. We never kissed it, we talked every night, and I now we aren't even we are not friends. I miss talking to him. Maybe I just wanted a little love in general.

part of essay,my homework2

This is the first time I've written/wrote such a long essay. I wish someone would correct it if I've made any mistakes~~~
:)

But I wasn’t feeling very sad at the time. because I had a new house, new friends, a completely new environment. I was happy because I could play with my friends after class. Though I miss him, I don’t go to see him often. Only on vacations or some special festival. 
After he was gone I realized that, for me, it’s only going to take me some free time, but for him it was a kind of hope (dream,disire?). A hope (dream,disire?) for me, a hope which (lasts forever?) needs a long time to wait.
I hate myself for taking such a long time to realize that. I feel sad when I look back on the old times.
I remember a spring festival when I went to see him. His body wasn't as good as the old days. He walked slowly to the kitchen and took (picked out?) some bananas, apples, and some candies which were my favorites. And he said: ‘ Honey, grandpa (saved these especially for you. I know how much you like these fruits. /?) reserve it for you specially, I remember you like those fruit.’
I just took it (him/?) for granted.
I never thought of losing him, never. But all of a sudden it did happened.
He didn’t have a lot of expectations for me, but I remember he once said, ('I hope that you will be accepted into a good university."/?) he wish I can admitted to a good university. Although my school work is not that good, I think that my grandpa, if he was still around, wouldn't be disappointed.
I want to make him proud.

(I hope I didn't change the meaning of your story.)
