帮忙分析一下这句句子的语法点并翻译一下

Question

I have discovered things along the way that i never would have seen had i not had the courage to try things that seemed impossible for a shepherd to achieve

Answer 1

（When I have been turly searching for my treasure, ）I have discovered things along the way that i never would have seen had i not had the courage to try things that seemed impossible for a shepherd to achieve
had I not had the courage 相当于if I had not had the courage
（When I have been turly searching for my treasure, ）I have discovered things along the way that i never would have seen if I had not had the courage to try things that seemed impossible for a shepherd to achieve
句子主干为 I have discovered things along the way，我沿途发现了事物。
（When I have been turly searching for my treasure, ）为时间状语从句，加上后译为：在我真心寻找我的财宝过程中,我沿途发现了事物。
that i never would have seen if I had not had the courage to try things that seemed impossible for a shepherd to achieve为定语从句，修饰 I have discovered things along the way中的things。这个定语从句中，引导词that作seen的宾语，这个定语从句带条件状语从句if I had not had the courage to try things that seemed impossible for a shepherd to achieve，这个if条件状语从句带宾语从句that seemed impossible for a shepherd to achieve，that在定语从句中作语。试着从后往前翻译如下：
hat seemed impossible for a shepherd to achieve一个牧羊人不可能获得的东西
if I had not had the courage to try things that seemed impossible for a shepherd to achieve如果我没有勇气去尝试一个牧羊人不可能获得的东西
that i never would have seen if I had not had the courage to try things that seemed impossible for a shepherd to achieve如果我没有勇气去尝试一个牧羊人不可能获得的东西，我决不可能看到事物
I have discovered things along the way that i never would have seen if I had not had the courage to try things that seemed impossible for a shepherd to achieve在我寻找的路途上，我发现了事物，这是 如果我没有勇气去尝试一个牧羊人不可能获得的东西，我决不可能看到事物。
（When I have been turly searching for my treasure, ）I have discovered things along the way that i never would have seen if I had not had the courage to try things that seemed impossible for a shepherd to achieve当我真心搜索我的珍宝时， 在我寻找的路途上，我发现了事物，这是 如果我没有勇气去尝试一个牧羊人不可能获得的东西，我决不可能看到事物。
以上是个人理解，供参考。一些完成时之类的意思没有细琢磨，也没有体现出。
