How do you rate the quality of a life?

What does one rate the quality of life on? Is it the amount you’ve loved? Is it how you’ve affected others? Is it the amount of wealth you’ve accumulated? Is it what you’ve accomplished? Is it the amount of love you give to the ones you leave behind?

I’m not sure. I think it’s the amount of lives that you’ve impacted through love and inspired through your work. I hope that’s what it is.
