I was about to complete with the very same thing, but I felt like I am asking too much if I had said to always improve yourself. This is of course what I wish for you and actually for everybody, only this way we will be able to build a better world, as in your description a world we all want to live in. Even though many times I think about myself and people like us that we may be too idealistic and that will never happen, but at least we can try and enjoy the results :D
