Let's put this another way. I agree that having to deal with negative people is draining. However, does fixing that require a big house? From what I know you don't need a lot of money (by Western standards) to find somewhere else you prefer to live. What's holding you back from living somewhere new (whether that's a new country or somewhere with fewer problems in your current country)?

What's the "self" in improving yourself? You as a human being (humanity)? Or your human condition (comfort)?
