I always find myself in trouble when I am trying to underscore the fact that some thing, as opposed to some other earlier mentioned thing, is in just the same status or situation. Interestingly, I don’t find it hard to perform the same task on persons, that is, when talking about people, but I always feel that I am doing something wrong while talking about things.
For example, I feel that the following three sentences are more or less okay:
Don’t tell me that Jack will give me some valuable piece of advice – Jack himself is in urgent need of advice.
Henry won’t be a good English grammar teacher – he himself needs to learn grammar first.
I’ve heard that you’ve had problems with your health and that you need some help with your job. Well, I am sorry, but I won’t be able to help you this time as I myself have problems with health these days.
However, I feel that there is definitely some problem with wording in the following three ones:
Don’t tell me that Jack will give me some valuable piece of advice on how to fix my house. He is no expert in this field. His house itself is in cracks and crevices.
Henry won’t be a good English grammar teacher for my son. I’ve read Henry’s letters in English. His English grammar itself needs a lot of improvement.
I’ve heard that you’ve had problems with your health and that you need some help with your job. Well, I am sorry, but I won’t be able to help you this time as my health itself is in trouble these days.
Is there any general guidance on how to go about such cases?
I've looked through several resources, but haven't found any that would specifically address this issue.
