Resonating Words

I have been immersed in a paper that I am writing for my PhD. I see to be reading continuously but my writing is limited. Partly, I want to cover everything about the subject. I am looking at each paper I read as a source and then I think about it too much before moving to the next one. my head is buzzing with ideas for my own project and I am very excited too excited and seems to be drifting with thoughts and when it comes to writing I feel limited as it will not convey my passion and will it should only cover the scientific facts
