Consider the value of your purchases, that doesn't mean buying the cheapest thing. It means buy the things that give you the most benefit. Price compare, don't just blindly go to the store and buy something.

Don't drive to the store to buy one thing. Go to the store if you're already going past it or need to do a full run.

If you think you want to buy something you don't necessarily need, don't buy it immediately, put it in your online shopping cart and leave it there for a few days, then decide if you still want it.

Sell stuff that you don't want or use anymore.

Never go out to eat/ order food if you can help it.

Stop drinking soda/energy drinks.

Stop smoking, doing drugs, and drinking alcohol.

Never go inside the gas station to pay, always pay at the pump. You'll avoid impulse purchases and don't buy lottery tickets.

Stop caring what other people think, you don't need to buy a bunch of fancy clothes, shoes, the latest iPhone, etc. The only time you need to dress nice is a job interview and special occasions.

Show up to work on time, don't complain out loud, and have a willingness to learn something new. You don't have to be the best to get more money. Don't stay at the same job if you're not getting promoted or regular pay raises.

Buy a bicycle.

Floss your teeth, dental work is expensive.

Move to a higher cost of living area to get jobs that pay more. Rent is higher, but everything else costs pretty much the same so you're better off and have more job opportunities.

Put as much money into your retirement account while you're young, time in the market is better than timing the market.

Take care of your things, especially if you have a car. Maintenance costs less than a new engine.

Learn to fix things yourself

Stay away from predatory loans from places like rentacenter, buy here pay here car lots and payday loans. Just don't.

Don't take out a car loan if you can't afford it.

Get a roommate and split rent.

Take the bus/train.
