I LOVE Google calendar! I can colour code each calendar, they've got sticker type things as a memory tickler eg. Money bag for pay day. I think I've got about eight calendars going, lol.
It sends you the day's schedule at 5:29 am each and every morning so you can see what you've got planned when you check your morning email
I'm not really so busy that I have to try to fit in people, lol. I live with Breathes, date Possibility and have one or two friends I hang out with on occasion, lol. Tuesday is my night with Possibility as Breathes works his second job that night
