Weightloss motivation

So I want to lose 18kg before I go to Europe, which is a little over 6 months away
And as I’m very easily strayed from a diet, I decided that I’d reward myself, every 3 kilos I lose with something that I’m not allowed to get until I lose the weight

-3kg:  hair dye
-6kg:  pretty travel wallet
-9kg:  new clothes
-12kg: modern family season 2
-15kg: the oc seasons 3&4
-18kg: full body massage + new clothes
