For example, do you track your spending in categories like: Groceries, eating out, clothing, etc?

I've never kept track of spending in any certain categories. I just started to track grocery spending this month though, and I will track through the year. I plan to just write down what I spend in my planner and add it up monthly and then add up the year at the end. This is more out of curiosity. I know what we spend in other bills (or I could easily look), because those are easier to keep track of.

I wanted to do it for non-essentials spending but I'm kind of scared, but maybe it would be eye opening...although we aren't big spenders to begin with.
