About 50 a month just for my food, more if I need some protein mix.

No car payments, income goes into investing in assets, like my book says. If not then this guy will come and break my knee caps with a sledgehammer.

If I cut the fat, in USD: (thinking of going back to school, so this is a plan)
300$ / month in rent (utilities included)
20$ / month gas
80$ / month amortized car repairs/replacement
30$ / month gym membership
150$ / month food
100$ / month books
18$ / month DVD rental subscription
----
698$ / month

I'm living on $0 a week right now. But I'm living with my parents and I'm going to university. I spend money but none of it is mine. :D. Huzzah.
