Definitively, you have to add articles to refer to abstract beings as subjects.
In addition to previous answers, I'd like to add that a phrase like "La Valentía vive aquí" seems a bit odd, I'd go for a expression like:
"El lugar donde vive la Valentía"
Here you change your subject from Valentía to aquí ("El lugar" --> aquí) giving more emphasis to the place (channel, program, place where it happens) more than the abstract concept of Bravery.
Depending on what are you trying to express, would be a better solution than a direct translation of an english sentence. Keep in mind that different languages have different ways to construct sentences and what sounds perfectly legit on one can sound odd on other.
