There's a hidden opportunity cost of Netflix though: instead of spending 10 hours a week watching Netflix, you could do something much more productive. Netflix is cheap, but it's also pretty much a waste of your time, you're not going to learn anything, and it doesn't satisfy: you always need the next series. If you quit smoking, you will not just save the money you spent on it, you'll also get more energy, no cravings, and not spend an hour a day smoking. That adds up really quick.
