I wrote a composition about my job ,Who can help me to correct mistakes? thanks O(∩_∩)O

Today i want to talk about my job .when i was a college student，my dream was to be a journalist. I studied hardly and stayed in library all day usually.I knew this work earn less money but i don't care ， i just want to write lots of news to everybody，to tell them what happend in china and many person stories.I hope my article can change the way people think about this things and what you think makes something valuable.After four years of university life and the accumulation of knowledge and prepared a three-month effort, my dream came true, I got first place in tv station exam. and i became a real journalist. at first , everything makes me excated ,i went to many places that i never have been there , also met new people everyday . but then , many problems came out .like some news i want to report ,but it has something to do with politics, nomatter how hard i tried,but it was all useless.like some people naver try to understand us ,they thought we can solve all problems .actually we can't .Sometimes, when people criticize or blame us, we feel disappointment.Now,i feel very tired ,i aways work overtime .i have no much time to have a rest and often feel sick.last week ，i want to ask for leave 1 day but my manager refused，he said i was more stronger than i thought，that's made me unhapp and angry .Now ,i started to doubt this job is really good for me or not .and what should i do ?

Please remember that when you are referring to yourself it is always "I" and not "i".
