To do lists

So, I'm a bit concrete random, so my to do lists no longer look like a traditional to do list. They exist, but in several places for several things. My random nature has kicked them out of my Palm Pilot, into my lesson plan book, and then onto random sheets of paper wherever I find to write them down. Apparently, I'm not alone!

I admit, when I am working from a real-life pencil and paper list, I will regularly add and cross off items I have already done just to have that feeling of accomplishment! How about you? How do you use a to-do list? Any good technological advice? I know there are to do list websites, such as http://www.tadalist.com/. I'd love to hear from someone who had used one.

I used to use a program in Palm that prioritized my to-do list by date due, category (home, work, school, etc.), and level of importance (1-5). I found that I spent more time organizing the to-do list than actually doing the tasks, so I gave it up.
