Draw a daily chart and account for as many hours and minutes as you can from last week. Include times you ate, slept, watched TV, read, commuted, worked, exercised, coached kids' soccer and wrote.
With a highlighter, underline all the times that are inviolate, e.g., eat, work, commute, church and family activities. With a different colored highlighter, underline all the activites that are necessary but flexible as to time such as walking the dog or grocery shopping. Finally highlight with a third color, activities that can be given up or traded with another family member...TV, menu plan, gardening, guitar lessons, daily trips to the gym or doing the dishes.
Look at the time you have free. Is it enough time to write as much as you wish? Can you organize your time better: menu plan and grocery shop the same time every week and only once a week or move your music lesson to immediately before bowling? If there still isn't enough time, evaluate your weekly schedule and make some choices. You may choose to give up watching DVDs or golf, trade chores with a spouse or hire someone to mow and shovel in order to give yourself more time to write.
Use your time wisely. While walking the dog or working out, record in a voice activated pocket tape recorder all the absolutely, Nobel prize winning, brilliant ideas that come to mind. Check to see if you can rearrange chores by shopping at off peak hours and buying a year's worth of writing supplies in August when there are back-to-school savings.
Value "gap minutes". Those are the times you stand in line at a store, watch a child's soccer practice or wait for the doctor. Take out your recorder or small notebook. Study people's mannerisms, speech patterns, social interactions and physical appearances. Make short notes so that when you get home, you have captured invaluable material to work into your stories.
After evaluating your weekly 168 hours and how you use them, develop an organized, realistic time schedule including as much time as you want to write. It may mean sacrifice. Do you want to "Dance with the Stars" or "Dance with Your Words"? Your time, your choice.
