you have to change your lifestyle if you want to save money, clearly the lifestyle you have now isnt doing it so you have to change something,
what i have started doing,
dont carry more than 20 bucks on you, recognize what type of consumer you are, impulse, conservative... what?? im an impulse buyer so i leave my debit card at home and have minimal money on me to avoid buying stuff i REALLY dont need.
figure out a budget, take your bills tally them up, and take your pay stubs and figure out how much extra money you have, i talked to my employer and my money is direct deposit into checking and savings.
dont buy fast food, $10, at kfc vs a $10 pack of meat at safeway, compare them.
dont stop drinking what you want, just budget and pay attention to what you have, if all else fails apply the $3 dollar theory, for every $3 dollars you earn, spend $1, save $1, and invest $1.
keep your savings habits after you get your supra done too, when you find a comfortable spending range where you have what you need the shit just compiles like interest.
walk, ride a bike, buy a skateboard (lotsa fun), youd be surprised how often women are impulsed to give rides.
