Organization

Ok, really. I am 31 years old and I CANNOT get organized. I don't know if it's because I have 3 other people coming behind me and unorganizing everything or if it's just because I can't do it!

Feel free to leave some organizational tips here for me to read and implement.
The first thing I have done is print off calendars so that I can write down everything I need to do. (Appointments, school, work, etc.)

I am a huge pack rat and am married to an even bigger packrat, so I'm working on de-cluttering and downsizing our belongings.
It just takes tons of time...which I really don't have right now.

I'm open for any suggestions any of you might have to help me get organized! I'm making this my 12th year of marraige resolution!
