Looks are as important as personality is, imho. You need to find your SO attractive but that only means attractive to you, not to the masses, ya know.
What one finds hot is not what another might. Take a hot sexy girl who is a bitch and no personality or humor about herself or life and can't hold a convo, she gets dumped. So that should tell ya looks are not everything to most.
Life is a song - sing it. Life is a game - play it. Life is a challenge - meet it. Life is a dream - realize it. Life is a sacrifice - offer it. Life is love - enjoy it.
