Do you have one of these?
It's one of those To Do lists; Mile long lists; Some things get done and some just get juggled around lists.
I have one and I finally decided to stop rewriting it weekly, monthly or daily as it sometimes gets done.
I finally realized that mine will never be a short and sweet, less than 12 items list. (That only took me several years of being a mom to come to grips with.)
Yup, I finally wised up and realized that I needed to formalize my list in order to simplify it.
This simplification actually freed up my process of getting things accomplished more readily.  
So what did I do to formalize and simplify all at once?
Why I typed it up on my trusty laptop in Word.
Now I have my "Never-Ending List" always at the ready. Yes, that really is what I titled it. That helped me get over the mental block I had of thinking I'd always get it completed. Plus I've stopped beating myself up over the fact my list grows at times faster than it shrinks.
I can modify it to suit my current schedule or future schedule as needed and in only moments instead of a complete rewrite taking several minutes as I once would have done.
I also like to date my accomplishments and use a different font color (much like crossing something off a physical list on paper).
That's really a great motivational tool too. That being able to look back at what all I accomplished in a week or a month. Oh it really does a mother good!!!
