If you're a seriously unattractive guy, you have two main options. Either become a comedian and learn to make every girl laugh all the time, or work hard and get rich.
Less dependable options are to date alcoholic girls or learn how to give VERY good massages.
On the other hand, just like you want girls to see past your looks, you could consider looking past a girl's exterior and trying to pull a girl who is right for you on the inside instead of one who just looks good.
