I read this article yesterday. Most of the stuff on that list I definitely can't live without. But among the things I've lived without for a while now are cable TV, smart phones, and going to the movies. But this is based on being a young, single person out of college rather than going through an economic recession.
I definitely think cable is a big waste of money. For one thing I never watched much TV to begin with even when I was little. But the programs I do like I manage to find online anyway. TV has become really accessible online in recent years. Not to mention you can luck out and skip through commercials or replay something you missed
I don't own any kind of smart phone and I'm OK with that. I'm more than content with my Verizon LG Cosmos since it's everything I need in a phone. As long as I can text, I'm good with what I have.
Going to the movies has become really expensive over the years, especially with all these 3-D flicks that have become popular. These days I almost always prefer to wait a few months for the DVD/Blu-Ray to come out or rent through Netflix or Red Box. Those have some great deals, and you don't feel so bad about what you've spent in case the movie you watched was crappy. Not to mention I love watching movies in the comfort of my home so I can get into my pajamas and get up to take nature's call leisurely.
I haven't cut out alcohol completely out from my life, but I seldom drink to begin with. I might have a boozy drink once every few months if there's some sort of social occasion. Otherwise, I don't ever really drink!
Otherwise, I've just adjusted some spending habits here and there. I started buying more off-brand products than I already had. I got into the habit of buying used books online or going to Half-Price Books for my reading entertainment. Fortunately I live near most everything in my city, so it's not really necessary to drive to many places unless the weather sucks.
