The world is actually never fair. The efforts and hard works, which we put in, would never resulted in direct proportional rewards. Therefore we all should look at things open mindedly.(I wish I have a big brother)
Factually this world doesn't contain any absolute equality, and since endeavor and gain aren't directly relevant, we can only view matters more broadly. (I wish I have a brother.) 人脑产品，呵呵 希望对楼主有帮助。
为你提供迄今为止没有错误的译文： In fact, there is no absolute fairness in this world. What you get may not be proportional to the hard work you've put in. Therefore, all we can do is to take it easy. (I want to have an elder brother.) 相信您会满意，祝你学习愉快！(*^__^*)
