How I compose a piece of music

How I compose a piece of music: 1) listen to what you hear inside your head, 2) anything else isn't music, 3) find inspiration, 4) don't listen to what others say about you if it's negative, 5) find some kind of method to shield yourself from your own music if you find that you can't get that tune out of your head, 6) never lose faith in yourself, 7) listen or read what the great composers before you have done/said/experienced, 8) you are your own person/entity/unique individual, everything you write will reflect that, 9) once you've found your inspiration, the longevity of the piece will last as long as you listen to it, 11) don't give one ounce of care to whether anyone dislikes/likes/or doesn't care about your composition.

The Orchestral work.

I'm being true to what I hear inside my head.
But at the moment, I can't seem to make it go anywhere.
It just get's worse and worse as I progress.
And if I replay it from the beginning I'm already sick of it.
Especially towards the end,
Which is where it's supposed to have some kind of romantic melody.
It doesn't sound like it's coming from me.
It's coming from random pretty patterns I see on the screen with no musical depth.
Perhaps I need to sleep on it before I can come up with a memorable melody.
And maybe it needs to last shorter than twenty minutes.
I'm starting to mix up the pop music I hear on the radio.
Is that remaining true to myself?
I'm not sure,
If I borrow other melodies from other composers it's not like it hasn't been done before.
I just don't want to be reproducing exactly what I've heard before by accident.

I have to keep asking myself:
What is it saying?
What feelings am I trying to evoke?
Are there superfluous fluff I'm adding onto it?
If so, delete the notes right away.
