There is no such thing as "ugly" in reality, so its not something to dwell on. You might think this is a self-help gimmick to trick you into thinking you're good looking or something, but its not. Really think about it. You are just you, a uniquely designed product of nature. The ugly label is only superimposed by the mind. Just remember that the what is supposedly ugly is a judgment of the mind which is conditioned by the society it grows up in. Ugly is 100% subjective.
In american society though, "pretty" is a commodity, so there's an emphasis placed on looks which can be made better by selling products. It's not an evil conspiracy theory, just how our capitalist society turned out, for better or worse. So don't beat yourself playing a game that can't be won. One of the greatest lessons to understand is that we must live fully as ourselves, not through arbitrary standards set up by forces beyond our control. You are all that you have. So simply offer yourself, as it's the greatest courage in the world. Open yourself and the world will open too.
