It depends on the culture. Looks are only important at the start but if you are a loser, you can forget about keeping a 10. The key here is that good looking people usually have every other attribute women find attractive. Confidence, social status, ****y, playful etc... except for maybe witty and intelligence.
Social Status is very important to women but its harder to demonstrate. If you cannot create attraction (playful teasing, chemistry connection, manlyness), then Social Status is worthless. Life of the party can quickly be Clown of the party. However, social proof will make her interested in who you are and what you bring to the table. You just have to make sure you keep her interested.
So in a nutshell, if you are a good looking guy it is much easier. I feel its more important if you are born with it. If you are not a good looking guy but have social proof, then you have your work cut out for you. Becoming well groomed, playful and acting confidently will work wonders for you but you have much more work than the good looking guy who most likely naturally gained these attributes.
