Even if you're happy with the life you've chosen, you're still curious about the other options.

The unexamined life is not worth living.

Beware the barrenness of a busy life.

The really important thing is not to live, but to live well. And to live well meant, along with more enjoyable things in life, to live according to your principles.

In childhood be modest, in youth temperate, in adulthood just, and in old age prudent.

The purpose of life is to bring forth goodness. Now, in this life.
