I didn't need Mint to tell me to stop wasting money on sneakers I'd never wear lol. I don't obsess over spending, but I like to track where my money is actually going at the end of the month and reallocate my budget. If I see I don't need to pay x amount for electricity or groceries this month, I'll take the extra and bump up my budget for something else.
My budget consists of rent, bills, living/work expenses, entertainment, dining out, personal saving, emergency fund, and investments. Any expense that I don't budget for (like a plane ticket, gadgets, citations etc) come from out of my personal savings.
If I'm eating out it's probably twice a week at most, but more than likely once every other week. Same thing with drinks. I don't need to be at a bar every weekend to enjoy life.
