How do you say, "A life lived in fear is a life half lived"?

Question

This phrase was said by the Spanish Granny in the film Strictly Ballroom.

Answer 1

My input would be:

Una vida vivido en miedo es una vida vivido en la mitad.

Answer 2

La vida vivida en miedo es vivida a medias

I'm not sure about the "en miedo" part. prepositions can be tricky.
