Ayn Rand: Can someone explain this concept without sounding selfish?

I have tried so very hard to read Rand. However, I find her writing style so tedious and (quite frankly) awful that I just cannot make it through an entire book. I hear lots of synopses on her Objectivism, however it all just comes across as selfishness to me. Now I would typically dismiss this as the fault of dreamer’s idealism, much in the way Marx’s universe is unattainable. However, are there any jellyfish out there that truly believe Rand’s world is attainable and explainable? I would love to here your ideas on the subject as long as you don’t mind lots of questions and possible critiques.
