I'm genuinely curious as we operate with a very extensive budget (an excel spreadsheet about 4 pages long), with about 5 separate bank accounts for the money to sit in to cover appropriate bills. Ie: a car bills account, a house bills account, a presents account, a medical expenses account and a 'new' things account (clothes, hair cuts etc).
This way when a bill arrives the money is sitting in the account to pay it and there is absolutely no difference to the money we are left with out of any given pay for spending. I couldn't cope any other way.
We are currently operating on the one income we will be when #1 arrives to adjust, I am only working casually and this money is being saved to give us a buffer when I'm not working at all.
