You are right thinking the way you did. If you are reading, there is something worth reading, which means that it is going to be informative and formative for you. It is this that you can exploit in your writing. What I really mean is that your state of knowledge will never be the same after something worth reading.
For most people writing is more difficult than reading. But if you read your own text you will discover that there are necessary some refinements, so you have to read additional books etc. If you work with peace and contemplation, thern "jiggling" is no bad path.
