You don't negotiate
From negotiating the price of your car, to negotiating your salary, you have a lot of potential to save thousands of dollars. Yet beware, negotiating is not something most people are skilled at.
I recommend buying books and then spending 1000x more time actually practicing the books teachings with a friend.
That's how you'll walk into a negotiation with confidence and ready to tackle anything that comes your way.
