Struggles with attention/focus….

Brooke, often when I sit down to do work that involves a significant amount of writing, I find that it can take me a significant amount of time before I really get into it (sometimes an hour or more). I outline prior (usually a day or two before), and will give myself 2 hour writing blocks. It’s a bit frustrating for half of that time to be spent, spinning wheels or gearing up to focus. Any suggestions on what I can do so that when it’s time for me to write, I write? Also, for context, this is legal writing for clients — all research and outlining is already done at this point. Thanks for your prior feedback, it was really helpful.
