Even if you feel you're too busy to plan, you'd be surprised how much time daily planning saves you in the long run. If you have to, get up 15 minutes early each morning when it's quiet and you'll be undisturbed. Write down your "Things to Do" list. Prioritize the items on your list, giving each an alphabetical or numeric ranking to show which are critical, which can be put off a bit and which are more long-term goals. It'll help you sail through the day.
Being organized at home is a must for large families. Hunting for keys, lost homework and the coveted pizza delivery menu can waste a lot of time. Establish a command center to put, and keep, your family essentials. A calendar to keep track of everyone's schedules makes a great reference when you're planning dinner. A place for sorted mail will ensure that you won't miss paying your electric bill. And don't forget to include a bulletin board to tack up important information you need to keep close at hand.
