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.

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

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.

Life could be limitless joy, if we would only take it for what it is, in the way it is given to us.
