What I want to know and learn about writing

I would like to improve my ability to write cohesively with confidence.
I need to be able to edit my thoughts before I commit them to paper.
My employment obligates me to write assessment summaries, case notes,
letters the courts,probation and attorneys. Although I enjoy writing I often
experience decision distress. I am challenged by what to include, what to omit
and how to organize it. I cross out way too much, which is certainly not
conducive to the flow of what I'm trying to convey.
I believe I will benefit from learning to structure my writing
on both the micro and macro levels . Practicing writing in an organizational
format will help me develop skills needed to communicate
clearly and accurately . The confidence gained will enable me to write decisively. This will likely help me to manage my writing time.
