Translation - Farsie-Persies-Engels - من به رشته کامپیوتر علاقه داشتم و برادرم در این...

Your original was: was interested in computer science and my brother was working in this field and I was sure about the future of this field and I was feeling I would be successful in this field, but unfortunately because of having two jobs I could not become successful in studying.

Too many "ands". In english to use a word like and too often is not acceptable.

that is why I explained, the original was too weak. It had used too many ands. nonetheless, the text was not modified. cheers

اصلاح متن
من به رشته کامپیوتر علاقه داشتم و برادرم در این رشته موفق بود به همین دلیل من هم به موفقیت در این رشته مطمئن بودم ولی متاسفانه به دلیل دو شغله بودن نتوانستم در درس خواندن موفق بشوم

this is a better original text.
