I guess successful life means a life we can content. And for that, we need money for survival, good relationships and health and we need to live life that we think is right. I heard that good relationship is crucial for happiness and health is important to enjoy life well. Also if we live life that we feel wrong it will be hard to feel content. The reason people think of much money and high social status first when we talk about success is they are easy to measure and compare. It's easy to think "The reason I don't feel content is I don't have enough money and social status. I will be content if I have that much money and high social status." But I think that the real meaning of success is a life that we can content.
