One of the words that I use frequently about the writing process is "messy." Writing is messy process, more often than not. We do not get to have our ideas easily actualize themselves into an article. It is hard work, with progress and problems, delights and depressions- it is messy. One of the hardest things for those new to academic writing is the messiness, or at least a willingness to allow for it, to take chances, to let go of an easy and orderly path. In many ways, this is normal, as new authors do not have the track record needed in order to feel trust in themselves, faith in the process. Expect that the process will not be smooth, linear, or easy, and you will not set yourself up for too-high expectations.
Learn to become ok with the messiness of the process- it is inevitable.
