Is this a description of Egomania?

I have always had some level of obsession with leaving some ridiculous legacy behind me. Whenever I focus my attention on any single goal, I become obsessive, and feel like anything other than total success is no greater than failure.

In Education, even though I am too focused on starting a career in music to study to excess, anything less than an A feels like failure. In music, I have no aspiration to be in a locally successful band, or even in a famous band, my motivation is to be in a band that becomes a pop music phenomenon, creates hysteria unseen by The Beatles, and inspires a socio-cultural revolution.

I don't feel like this is Egomania because I don't think that I'm worth, or deserving... or even capable of achieving something even close to being on that scale. And an Egomaniac if I'm correct would be more self-confident than that? So what is it?
