Budgets can be found in one's everyday life. Every time before you visit a grocery store, do you decide which items you need and how much you need? For few items, do you even decide whether you should keep in surplus on hand for emergency. Do you also keep a mental note of items (and their quantity) that are there at home. If your answers for these questions are yes, then you are implicitly making a purchases budget for groceries. Now, think of other budgets that you prepare.
