麻煩幫我修一下，令以下這一段英文寫得更好！

我曾經讀過一本英文書，也略略談到如何寫求職信；書中提到，求職信最重要站在”那公司”的立場看事，並你能帶給這公司有甚麼好處。在你這求職信裏，全都是從你的好處看事情，如：I can learn many things in eyewear industry，並eyewear industry has good prospect in the future. This reason makes me decide joining eyewear industry.（即你只是為著你自己的前途著想，故求此職）
我相信，若你以此為求職信，逆地而處：你若是老闆，看到這信，也會很快掉進廢紙蘿。所以，我建議你要重新寫過另一封，而內容是談及你如何能帶給那公司的好處。
如：你以往的經驗，你勤力、認真做事的態度（因為你肯到知識不恥下問，看出你做事頗認真）；你對於從事於eyewear這行業的熱誠；並你如何看好這行業的前景，並希望怎樣能發揮你的所長，以達到公司與你兩方的得益。
不如你再寫一封，再補充在”知識”的詢問，那時我再為你改。因為現在為你改，你寄去，反而是害了你，希望你明白！（因為我希望能真的幫到你，而非為的分數）
