It would definitely help if you bought a new pen. For me the inspiration lasts for at least 5 minutes.

I read something long ago that you may enjoy:

"The notebook should not be a chore. It should not be a duty. It should be freewheeling with its purpose shifting and changing to the delights of the writer. It should be a volume of dreams. Not a volume of tasks. It should be a place of fantasy, whimsy, and imagination. Write in it. Draw in it. Doodle in it. Use black ink and red and purple. Use a pencil. Use a crayon. The notebook should be a place to poke around in the dark or in the brightest light, a place to survey the brain, discover the deepest thoughts or the silliest realizations. Write in one notebook or write in dozens. Keep one there and one over there. By the bedside and in your pocket. Own them. Love them. Cherish them."
