You chicks' rewards for reaching your goals sound great! Gel pens are AWESOME.
I am hoping to be able to reward myself for every 5 lbs. lost, as well as every 5% and 10%. Positive reinforcement goes a long way with me.
So far I've been to a movie and bought myself a comforter for my bed (nothing fancy or expensive, just something to keep me warm).
Future reward plans include buying CDs and DVDs, going to see movies at the theater, buying body mists/perfumes, and new sheets. For major milestones I'd like to purchase some more expensive items - a shotgun, an acoustic guitar or banjo, etc., but that will depend on my finances.
Clothes can be great motivators, but I don't think I want to invest too much in them until I'm a much lower, stable weight. I'll probably (hopefully!) have to put together a nice professional wardrobe, but I think a nice non-work wardrobe might be a good reward for maintaining half a year, or something like that. Do any of you feel similarly?
