Two methods that I used last week to keep a sharp focus were  - assessment cards  - Taskmaster    These techniques were useful but only if I already knew what I was planning to do.  If the plan wasn't fully laid out in my mind, I can't use these techniques for that kind of stuff.  I feel stuck sometimes.  For example past 4 days were eaten up by a phonecall from a family member who created some new drama.  That consumed a lot of my time.  Plus this month the weather is too cold and depressing and I tend to suffer from winter depression or seasonal affective disorder.  I get sluggish in winter. It's hard to focus if it's cold outside.
