Nhờ sửa bài giúp

I began to studying English for a long time ago, about 10 years, like all of people in my country at the school.

But without conversation practise with native speakers it was not so effectively, and of course i wasn't so serious about this.) Good English knowledge gives me some opportunities and benefits for my job, traveling and meeting with some interesting people from around of the world, I think that.) P.s: please correct me, if it no difficult for you)
