lots of great advice here. let me add, keep track of your expenses for at least several months. be meticulous.
for instance, separate out food, liquor, cleaning supplies, paper/plasticware, toiletries, etc from your grocery receipt. track your spending on packaged snacks, such as candy bars, sodas, chips--all that impulse stuff that adds up. break down your travel expense into categories--taxi, bus, gasoline, car repairs, auto registration, insurance, bicycle maintenance, etc. you get the idea.
start this now, so you'll have a clear idea how to budget for your needs while you're saving that big new salary!
