I function best with lists.

I have lists for all kinds of things - especially for things that are regular.

We have a house in Arizona and I keep a list of the things to pack before I head down, especially bike related stuff.

I now have a list - printed out and in both the garage here and in Arizona - laminated - with the checklist of what needs to be in the car before I pull out.

Just for good measure - I have the list on my blackberry as well.

Checklists are often the only things that save me.
