If we are talking about having a good life then surely that should be related to having a lot of money. However, I think that those who are a millionaire or a billionaire might that have the true quality in life. This is due to the fact that they are really busy in their life so therefore they don't have time to rest or chill out. I think that the nature of good life should be something like having 100% freedom. This means that you should have time and can do anything you want that makes you happy.
I would say that having a passive income is the key element that will make a really good quality in life. As you don't need to work and earn a lot without making you tired and allow you to have financial freedom and so you could buy anything as you wish. Moreover this leads to not having diseases or cancers because every day you eat foods that are good for your health and also have time to exercise which minimizes the risks of getting those dangerous diseases or cancers. Moreover in my worldview I think that it will make perfection you could do whatever you want without having anybody to order or force you. Lastly, if you have what we called "true love" and "true friends" it will hopefully make you have a better life. And at last you will acquire the true quality in life.
