Sanzai.co.jp 散財 Money Logging Starts

I was inspired by a young millionaire who retired at 30 years old. She worked for 16 years of her life, and she had many notebooks detailing every single dollar she spent. "I want to know whether I have spent or saved each single dollar."
The idea was very interesting. I did some book keeping on my spending before, but I never could tell where every dollar had gone.
Yesterday, I saw my friend has a sanzai list on her blog, and I thought it would be nice to give it a try.
I can input my spending through browser, or simply sending an email with a few lines. Let's hope I can keep up the effort of logging m spendings.
