I try to stick to my daily plan -- I write in the morning and edit in the afternoon. I take a break for lunch of an hour and a half. During that break i also run whatever errands I need to do.
Time management is one thing I need to work on it is my nemisis~ I simply don't have enough time in a day to complete everything.
I've tried schedules and I become stressed when I can't meet them and eventually something loses out~ Mostly it's my writing. Also I have to learn to say no to things! (leaving more time to actually manage)
