What motivation methods have you used?

Back in 2007 I told my father that I'd like him to not send me birthday and Christmas money like he usually did, and to save it up for when I reached my goal weight. 5 1/2 years later, I reached goal weight and got a lot of money to buy a smartphone (I subsequently rebounded by 9kg and have started losing that recently).

If you've done something similar, I'd be interested in hearing about it. Thanks.
