hey, i have an idea...
wheneva ur gf complains about not havin enuff money to spend, ask
her if she has any idea where she's spending her money.
I usually have no idea where exactly my money's gone too
but i noe that they're mostly spent on food
as for wat type of food, i'm lost

wat i usually do, would be to record down ALL my expenditures. in
exact details.
like 1.95 on mac's tempura chicken lar...
0.70 on barley drink lar etc
every little thing i buy, i record them down.
then at the end of the mth, before my next pay, i'd take out my
records, and do some self-reflection.
Did i overspend on stuff that i have absolutely no use for?
How can i justify my spending? Are they necessary? Is there a
cheaper alternative? etc
and then, plan a budget of some sorts....
oh ya..
remind her how exp everything is in sg when it comes to settling
down... 
liek the reno of ur flat? the cost of havin a banquet, photograph
shoots etc...
and if each of u are gg to save up 200 a mth, which amounts to 400
per mth, it would take around 50 mths for u to save up to 20k..
which is barely enuff... for the wedding package, or renovation for
ur new place...
unless u wanna take up a loan. and then, ur take home pay every mth
after cpf, will have to go towards repaying all ur loans... such as
home reno loan, ur furnitures, if u opted for instalment, ur
electrical appliances too..
then there's savings to be placed aside for ur kids if u wanna have
one...
and also.. if ur cpf is insufficient, u need to top up the
repayment with cash..
that's a lot of money u noe 
damn.. i feel so depressed
