I agree with other posters that the element of surprise is key.
For awhile, I put a quotation which I had always found extremely motivational up on my wall above my alarm clock when I had a consulting gig that required rising at 5am, seven days a week. Instead of gleaning inspiration from it, I started to just block it out.
I *love* HassleMe. You can set it to send you email reminders at random intervals. I have one set that says "Just breathe" that pops into my email once every week or so. It always encourages me to take a moment to relax.
I also keep a "refresher" tag in del.icio.us with posts, quotations, etc. that I want to better internalize. I intentionally do not schedule "Look at refresher tag" into my otherwise very scheduled life, but whenever I log into del.icio.us for other reasons (often) I'll be drawn to click on it and look around.

Yes, those links are on GtD Connect. I was signed onto GtD Connect when I originally read the posts. I didn't realize that they were part of a different (non Connect) forum when I posted my reply.
Sorry about that.
