I tend to live fairly frugally, I believe. Everyday I bring a lunch to work, My GF cooks our lunches and I pay for 2/3 of the cost. It's a wiin-win, she eats $2 lunches, and I eat $4 lunches with plenty of protein in them. I don't go out to drink, I spend maybe $30/mo on booze at home, and we only eat out once or twice a mo.
Where I fall off is buying tools and materials so that I can do jobs/repairs/stuff at home, that and I am slowly working on adding a bathroom. I always justify these costs. I recently spent about $800 on my cars body, which I also justify as needed. If I need to fix it, I should buy it right? Maybe I just need to deduct those costs from the amount I spend on frivolous shit, instead of throwing it on top.
I figure, most months I can save about $500-$1000.
I think I may throw $1300 at the house before the end of the year, that will take it down 1%, and I will still have money for a good furnace/installation, plus a small left-over cushion.
