How do I create a budget I will actually stick to?
Start by tracking every dollar you spend for two to four weeks before building any budget. Most people fail because they create an idealized version of their spending rather than one based on reality. Use your actual bank and credit card statements to categorize what you truly spend on food, entertainment, subscriptions, and so on.
Then build your budget around those real numbers, making small reductions rather than dramatic cuts. Automate savings immediately when your paycheck arrives so you never see that money. Use a simple system you will actually check, whether that is an app like YNAB or Mint, a spreadsheet, or even a notebook. Review it weekly for five minutes to stay aware and catch problems early before they derail you.
