How do you prioritize tasks?

Do you mark everything high or highest priority?  I've avoided that trap, but nonetheless, it just means everything is Normal priority for me.  Unless I attach a due date to something, its easy for it to slip off of my radar.  WebWorkerDaily has a short post describing one way to prioritize your todo list.

About a week ago, I noticed that my task list had this distribution for prioritization: 95 percent “highest,” 4 percent “high,” 1 percent “normal,” and no tasks at all at the “low” and “lowest” priorities. Is this because I am so important that everything I do is of the utmost importance? I wish that were so, but no. It’s because I’m not being realistic about my prioritization. That’s my dirty little task management secret.
