Favourite quote from this article:
"you don’t get to be the best-read man in America by giving a damn about someone else’s taste. You buy and read books that entice you for small reasons like a good cover or an intelligent introduction, books that appeal to your eccentricities. You keep as many books as possible nearby because they are in fact the very record of your eccentricities."
I think that generally, one should follow one´s heart. In all matters.
