Visions of greatness?

Hello few, I say few, because that is more fitting for this blog(although, I am very grateful for the visitors I do have). I have recently found myself at a very intersting crossroads. I am constantly caught between the desire for greatness, and the simplicity of mediocrity. In my heart, I long to change the world, but in reality, I just want to live an above average life, and be left alone. Where do I go from here??? I know that I have greatness in me, but it seems that laziness and apathy, are always the dominant traits. I am really at loss, so if anyone has any comments, they are more than welcome. Thank you few.
