用How I Change写英语作文

How can i change myself?
Today i made a mistake.Because this is my first time to deal with the shipping document after my back,and meet some problem,so i didn't check it with my leader,and then i made it.But sometimes i confused,somebody who has already deal with it for one year,he should know how to deal with the case like that,he didn't mention,just said don't know.Really strange.So now the trouble work here is they just do the work without thinking ,just like what our boss told us.And this is still his headache point.How can lead the other people thinking well before they do the work?I have no idea either.Just say good luck,Eliza,and try to do if you can do.
