I agree with everything you said except the last sentence. There is a saying in economics: "If there's no growth then there's no life in it." If we are not making things better then our life will not stay the way it is, it will be getting worse. So, basically, we have no choice but to grow. We should be improving our knowledge, our income should be getting bigger, and our living conditions must our living conditions must improve along with it. We must be moving forward, we can't afford to stand still.
I may not have conveyed my thought very accurately, but I meant exactly what you said - if you want improvement - change, become different, change your habits, improve your knowledge and skills. Without changing yourself, your life will not change.
