As I may be accounted for as a cynic for saying such a thing, I believe looks are illusions created by the feeble and limited human psyche, and we try to convince ourselves that "natural" physical attraction is indeed the virtue love. All preferences are placed into our bodies from the moment we are created, and henceforth I for one would agree that looks mean absolutely nothing, because in the end, if the only quality we desire is that of a physically and sexually appealing member of the opposite gender, we are only deluding ourselves from what we were intended to focus ourselves on...

Personality is different from physical attraction; if you grow fond of one's personality before their looks, then you can truly notice the person's reactions towards events or difficult situations. If we marry one of the opposite sex because "he/she's handsome/hot", then we do not have any idea who the person is, just that we like what we see and not what we know. If the one we love is one whom we know and accurately predict, then chances are that you have made the correct choice indeed.

Thank you and have a wonderful rest of the evening!
