否则你意识不到会犯同样的错误or you will ignore that you will make the same mistake 对吗？

对，但这样翻译更顺：

Or/otherwise you won't realize that you will make the same mistake.

改为or you will never realize that you would make the same mistake 会不会更好些？

我觉得
Otherwise, you will be aware of the same mistakes
如果写成这样就跟好啦

Otherwise, you will be unaware to make the same mistake.
