There are as many good and purposeful lives to live as there are people to live them.

I am indebted to the grave for this sentence on life by British philosopher A. C. Grayling.
And Socrates for the final words on what constitutes a good life.
I highly recommend his various speeches on morality which can be found on YouTube. My favourite: https://m.youtube.com/watch?v=-LyTc7Vh8zo
