Ok, a crazy idea just popped up in my head: to reward myself for losing weight with computer gear.
The idea is, that for every 100 grams that I lose, I get 10 euro's, that I can spend on building a new computer. I am planning to build one anyways, so it's not like it's costing me any more money, but it makes me feel like I earned it (and vice versa it helps me get some extra motivation to lose weight).
To make it extra affordable, I try to earn some of the money by selling some of the stuff that I have. I estimate that I can fund a quarter to half of the price of the computer this way (which, when finished, will be over 1000 euros).
Also, I have started a career as a software developer (which is a shift from my university studies) and I have my own small business on the side, which has been dormant for the last 12 months, but I plan to awaken it again by allowing myself to do some side projects, starting new year (so I can earn this computer back, and some extra). A computer is my main tool of trade, so I see it as a good investment.
I read in a book that I am close to finishing now that it's good to start with giving yourself a few points already. So, I will start counting down from 92.0 kg. My current weight is around 91.5 kg, so I have already earned my first 50 euros. I don't expect to go lower than 77.0 kg, so my eventual budget will be 150 (times 100 grams) * 10 (euros per 100 grams) = 1500 euros.
I have a few business ideas that I want to start (or continue) executing once I have a good computer at home, and I hope to earn this investment back at least a hundredfold (I believe in my ideas

).
