Thing 8 and 9 are all about organising yourself, first up is Google Calendar. I already have a google account and so have the calendar, but I use the one on my Blackberry instead. Maybe when I get a new phone next year and it isn't compatible with that I will change my mind and use the google one instead but for now I'm content not to change. There's no one I need to share it with, my life does not have that many demands!
Thing 9 is Evernote - a really great looking tool for keeping track of things of note online or on your desktop. For it to be useful I think you need to spend a bit of time practicing and creating a collection of notes on there to get it going so I think I'll make that a project for a day in the Summer Holidays (4 weeks and counting!).
