Hi,
No, that is not the correct way to write the sentence. The sentence contains grammatical issues.
I believe, the correct sentence structure is:
Charlie was mildly amused at how careful Jared was with his appearance; it just wasn't Charlie's way.
But, in another perspective, no change could also be correct.

Answer: “However, chores are building blocks for a firm foundation.”
Explanation: Metaphors are when the writer compares something to another thing by saying that they are or is. "Chores are building blocks" is comparing chores to building blocks with "are," so that is the metaphor.
