The struggle

hmm . .so I have really been struggling to try and work on my time and scheduling myself time for this, that and the other. I get a good plan worked out and BAM, something comes up.
Miss Chatterbox has a bad day and needs constant attention, I need to take so and so to this, hubby has a ton of homework and cannot help with anything, a volunteer gig takes way more time that expected, taking someone to the airport and on and on. I absolutely have no problem doing those things - this is not me complaining about having a gazillion things to do. This is me wondering what on Earth I am going to do to make a schedule work?!
Agghhh! I seriously have all these wonderful ideas and fun projects ... things I need to research for the cleaning stuff and books to read to get even more info on herbs and essential oils ... new items to put together for my Etsy store and blogs, networking sites and social sites to keep up with ... kids to take to appointements and take to and from school ... kids to rad to and spend time playing with or crafting with ... dishes to do, rooms to clean, clothes to fold ...
In otherwords all the gazillion things every mom has to do everyday. I just can't see to get a schedule to work for me! And if I don't schedule then there are certian things that I just simply don't get done and those things tend to be the creating things.
Anyone out there in mommy crazy land have any ideas?!?!?! It almost seems like now that I only have one at home it's harder to get things done.
Anyway, I would love some hints and ideas that you might do to try and get things done.
Timers, charts, hour-by-hour time schedules . .etc. Then how you work around big interruptions ie taking 4 hours of your day to do something to help someone that you had not planned on.
