Most people living paycheck to paycheck can't realistically jump straight to a 3-6 month cushion, so start smaller - even $500 or $1,000 makes a real difference when an unexpected car repair or medical bill hits. The trick is finding money in the cracks: cooking at home instead of grabbing takeout a few times a week, checking subscription services you've forgotten about, or selling stuff you don't use anymore. Once you've got that starter fund built up, you can reassess your budget and gradually work toward a bigger cushion, but having something is infinitely better than nothing when you're living tight.
