Some people need a mess before they can create, others need to be neat and orderly. And even though I often feel like I am living in a mess I do class myself as being in the neat and tidy group. I like clean tools and a tidy workspace and I like lists; to-do lists, to-buy lists, event planning lists. I think you get the idea?
I love calendars too and cannot live without mine. I remember the days of years ago, of being single and not needing a calendar, but today I like to make a note of EVERYTHING. And I like it like that. I like to see how my day, my week, my month and year is expanding and shaping. I use a combination of an online and paper calendar - it works for me.
If you would like a version of my paper calendar here is a link to download a 2012 calendar created by myself, to be printed on letter paper - totally free - enjoy!
