It ain't pretty, but here's how I got through it until I started bringing in good money:

1. No takeout or eating out ever
2. Get a water filter pitcher and a nice water bottle. Drink only water.
3. Every paycheck, take out $200 or whatever you can afford. This is your "fun and gas" money. Your gas, hobbies, social life, and dating comes out of this fund. Whatever is leftover when your next paycheck hits goes into savings.
4. If you can rent a physically smaller place, do so. It will save on utilities.
5. Don't buy a car unless public transportation or biking is not viable in your area.
6. Meal plan with the goal of zero food waste. So if you plan to buy an onion and will use half of it in one meal, make sure you have another meal planned that week that uses the other half. Do this with every ingredient. If you're careful and creative you should never have to throw away food. - On this note, get good at cooking. It's much cheaper to cook from scratch.
7. Cancel your streaming services and learn to pirate safely.

This works but isn't a great way to live. You need to combine it with a plan to either make more money or relocate to a cheaper area while maintaining your current income.
