I hear you! "Getting it done" can be extremely difficult.
In some ways, I am blessed to be (a) self-employed and working from home and (b) married to somewhat of a night owl (and I'm a morning person), which means I can have the first two hours of the day to myself.
I find that discipline matters, and especially the part where I have had to embrace the reality that the world will not "fall apart" if incoming emails to my various businesses get looked at at 9:00 instead of 7:00.
I think the most important "tool" (if you want to call it that) I use is that of only "rough drafting" during my dedicated writing time. During my morning two hours, only the creative is allowed... no editing, re-writing, spell and grammar checking. Just get all the key concepts under a heading down in some form of (often lousy) English. I can edit and clean up stuff while there are distractions, easy enough. It's the creative part that suffers.
Excellent point! And that has always been one of the hardest parts of writing for me. It took me a really long time to learn not to pick at every sentence (sometimes every word!) I write, as I'm writing it.
Working at home on my own projects, my own business, is the part I'm trying to achieve.
