I'm not sure if the ratio of inspiration/perspiration is 1:99, but I think it's important to realize that this is different for every composer and we all have the ability to improve both of these components. One of the best ways to become inspired (and become a better composer) is to give yourself the tools to do it. I do this by exposing myself different types of music, and acquainting myself with new musical instruments when possible. It's not really about talent. Talent is just our creative capacity based on our previous experience. (whoa, I got philosophical!) On the other hand, composing is a lot of work and there is not getting around that. If you want to compose great music, you have to COMPOSE great music. What I mean by that is, if you want to write good orchestral music, you need to start writing for the orchestra ASAP! Giving yourself practice in the genres you wish to write for is the best thing you can do. I'm not saying I've become a great composer by doing this, but I'm am becoming more satisfied with what I do on a personal level as a result of my endeavors.
And if anyone tells you you're writing boring, simple, melodic music...that is their opinion! It is a sad state that we are in today that academic centers pressure us to compose complex music. Write simple, beautiful music for yourself...and when the time comes, try to do it their way too...it's for your own good in terms of development.
I hope I've said something enlightening here...it was enlightening for me to think about!
