I read a paragraph that describes people don't exert control over their lives and let their lives get worse. It said, "If you think: I wish I had a better job; I wish I could leave thiss bad relationship; I wish I could complete this project. And so on and so forth. These are the collection of statements echoin gin the heart of one who lacks control."

 

Collection: many similar items put together.
Statement: a phrase that someone says, a declaration.
In this case: many phrases that describe one's wishes about his life, put together.

they have their focus on the wrong point.
Your list reflects someone focusing on the negative aspects of their life.

They need to focus on the job they want not the one they have.

Focus on the type of relationship they want and not the one they do not want.

Focus on the completing of the project and not what if the project is not completed.

just Focus....
