A mundane sort of post about losing weight

I do not do well with schedules.  I'm one of those people who will follow a diet and exercise program rigorously, to the point of obsession, for about a week.  Maybe two.  Then I start to reward myself for doing so well.  Not that food is a reward, really.  It should be about survival.  I WANT it to be about survival.  I do like to enjoy what I eat, but my new mindset needs to be that it is fuel.  
I've considered a juice fast, but I'm not entirely sure what I did with my juicer.  Also, I think that would go terribly.  I like to chew things.  That's what teeth are for.
Here's my new idea (my new AWESOME idea): I am going to write down everything I ought to be doing onto slips of paper.  I will then put those papers into a hat and mix them up and pull one out every morning.  I will only do one thing each day, but I will do it WELL.  I'll have an exercise pile, and a food pile.

Some examples:
no sugar today
no sugar including fruit today--add more veggies
no carbs today
green smoothie for breakfast today--heavy on the 'green'

p90x cardio video today
40 minutes of laps in the pool today
1 yoga session today
walk to classes today instead of taking a bike, take the long way
no internet except for schoolwork today

If something really doesn't work with the day's schedule, I'll just put it back and pull out a different one.  I think it may work, because it's so unpredictable.

Any suggestions on things to add to my hat?  Any ideas for a ritual/spell I can create to stay focused?
