It's never fun to pay bills. But many more of your recurring expenses are up for negotiation than you might think, according to Ramit Sethi, author of the New York Times best-seller "I will teach you to be rich."

Sethi says people don't try to negotiate their bills for two reasons: they feel uncomfortable and scared or they get too angry.
"Negotiations should not be adversarial," he says. Instead, "Come prepared with the length [of time] you've been a customer, other offers that competitors are offering, and be prepared to walk away if you don't get the deal you want."
Here are four bills that you can work to lower, and tricks for how to do it.
