low in cash...low in motivation

i've been low in cash for this week, somehow sort of spent more than my budget for the week during the weekend itself. Haih, how money just goes missing everytime u withdraw it. Come to think of it, i don't really have much cash to eat out or buy things that i want or saje want to buy because it's cute or nice. See, every week groceries and marketing sum up to almost 30 to 40 dollars, so if i budget only 50 dollars a week, then i only have 10 to 20 dollars remaining. Then i eat in uni for like 2 or 3 days [depending on how much money i got], at least like 12 dollars there i think. Imagine how poor i am, sometimes so sleepy and need a coffee, but not willing to spend so much, so in the end buy coffee from Donut King and get 2 free cinnamon donuts. Just enough to last me til the end of the day. Then we normally eat out on Friday, just nearby though, because so many people want to watch American Idol at 7.30pm. So sad to say, i believe that every week i spend more than what i budgeted for. Water bill haven't pay, 40 dollars, electric bill 70 dollars, phone bill [by credit so don't care]. But obviously it's all divided by two cause sharing with my housemate, Frances ma. Everytime compare bills with Eugene and Faiz somemore, their water bill 20 dollars, electric bill 50 dollars.

Potential reasons for differences in water bill:

^ Do not cook cuz they cook and eat dinner at our place

^ Therefore do not need to clean the dishes after dinner

^ Do not wash their own clothes = use washing machine for everything

^ Clean up cups laying all around the place probably twice a week [coffee cups everywhere]

^ Guys got short hair so don't need to waste water to rinse off the shampoo

p/s: Is that enough to account for the double amount in water bill?

Potential reasons for differences in electric bill:

^ Does tv not sonsume any electricity? [they have a tv and we don't but why their bill so low?]

^ Does electric piano consume electricity? [Frances plays piano everyday]

^ Does leaving the laptop and computer on consume electricity? [the gals do but the guys got no internet so don't need to use computer]

^ Does the fumehood run on electricity?

^ Water heater? Cuz we bath longer so should use up more also right?

When i say low motivation i was referring to studies. Still slacking off in studies, no motivation as usual, and always feel sleepy when it comes to studies. What's more i think i'll flung management cuz stupid tutor gave me low marks in my assignment that is worth 30%. I thought i did better than the marks she gave me. By the way, more geram that my assignment wasn't mark by my tutor. Stupid lady don't know how to read English! Keep on say my "sentence does not make sense". Stupid!! What's worst is that i put in so much effort into this assignment and this is what i deserved? Not like they said that i'm totally wrong, i guess i'm just not good enough huh!? So gave up hope on my management subject liaoz. Stupid ppl who ask me to take management! I hate management! I don't need to learn to be a manager, my dad didn't so why should i?
