If you want to start a business or find a flexible job, but already struggle to fit everything in, here are a couple of things I have found to help you get organised. I use the Life Book Diary from Organised Mum. They have a range of pocket diaries, larger diaries, wall calenders etc to suit most people, and lots of useful lists, pockets and space for notes too.
The other thing that helped me get out of post-baby chaos was signing up to FlyLady. Once you have got past the americanisms, it is a great way to give your life back some structure, and take control of the house rather than letting the chaos control you. I still love the idea of the 27 fling boogie, where you chuck 27 things in a bin bag while dancing round the house singing ‘Please Release Me’.
I hope one or both of these help you as much as they have helped me.
