How Great I Art? Or are these thoughts delusions of grandeur?

Sure, there's always some opinion out there that works against my inner psyche. Hell, I thought I was going to be great, I still do. I still think I’m special in my own way.

I have three books I wrote, but nobody has read them. I've written some illustrated children's poems lately. But what to do, what to do? How am I going to stop dreaming of great things to come, and why would I  do that anyway?

Here's what the Physician's Reference says on the subject:

Mania may also include . . . delusions of grandeur. Delusions associated with mania frequently center around an expansive sense of self that goes well beyond narcissism, eg, believing oneself to have special (eg, supernatural) powers or to be the chosen leader of the world or universe.

Accoding to the DSM-IV TR (the latest version) one of the symptoms of bipolar mania is:

Inflated self-esteem to levels of grandiosity

But what about all those self-help tapes; Tony Robbins, Denis Waitley, Earl Nightingale, Bob Mowad, Napoleon Hill, et. al.

Sales has been my career, not of choice, but that’s another story. It’s competitive and I was/am good at it. Okay, I was good at it. I never did like talking people into things they didn’t want to be talked into. I guess that means I didn't like sales, but I did the whole books on tape thing of the above genre for a few years and it did make a difference. I was an over-achiever.

Or was I just smart enough, and talented enough to let the bipolar delusions of grandeur build up my expectations and left me crashing down when I should have been reaping the fruits of my labors? I often felt it was self-fulfilling prophesy, setting myself up for the fall. Boy, I hate that term. Accuse a depressed person of realizing self-fulfilling prophesy and you'll get their head spinning. If I have negative thoughts, they'll happen? Mix that with the whole positive thoughts from the greats and I had two choices; be hypomanic in my approach to life, whereby good things would happen or be depressed and the world would cry with me. 

WTF?
