What I mean is, for things to change positively.

For instance,
A person suffering through a depression who wants to overcome it should change their views and their attitudes in order for them to make a successful recovery.

Or,
Someone who doesn’t have many friends because of his roguish behavior and no one trusts him, should change his attitude and be more open and polite in order for people to respect him.

And even in a bad neighborhood or apartment complexes where there’s constant evictions, violence, threats, and drugs involved and the community and managers need to change their attitudes to make it a safer place.

Also if a high school student is failing and doesn’t really care, but notices that because of his carelessness, it’s tearing him and his family apart and getting him nowhere in life except with people who make even worse decisions such as doing drugs or being apart of a violent group. He should change his attitude and get his education in order for him to feel successful and happy.

So is it true, in that sense, that you must change your attitude about certain things in order to make a positive change?

Or is there another way of explaining it?
