There was a time when I used to prepare a budget, even going to the extent of keeping money aside in different envelopes, marked with what the money was meant for. I would also maintain an expenditure diary and would religiously jot down every single rupee that we spent.
However, over the years I have learned the art of managing money and have hence stopped budgeting. It is I who do the monthly shopping, so I know our monthly expenditure is of an X amount and we withdraw that amount from the bank, each month. We do not cross that sum, and generally have some money left at the end of the month, that I carry forward. So, basically, we spend within a budget, without actual budgeting.
Underestimate me...that'll be fun!
