What mental accounts do you have in your mind about purchasing products and services Do you have any rules you employ in spending money?

I typically have mental accounts for essential expenses, discretionary spending, and savings. For essential expenses, I prioritize necessities like rent and groceries, while discretionary spending is reserved for experiences or treats. My rule of thumb is to avoid impulse purchases, and I often apply the "24-hour rule"—waiting a day before making non-essential purchases to evaluate if I truly want or need the item. Additionally, I aim to save a certain percentage of my income each month to ensure financial stability.
