You don't need to cut out entertainment completely in order to live a frugal life. Below, I have listed some very inexpensive ways to save money and still have fun.
If you live in a city, just try walking around. In New York, I have found impromptu concerts by street musicians or just sat in the park and people watched. You'd be amazed how much fun you can have!
Instead of eating out or going to bars with friends, host a potluck at home or just have friends over for drinks. It's much cheaper to buy liquor than to buy drinks at the bar.
For movies, go to matinees or the two dollar movie (a number of communities have them). Yes, those movies are second-run, but hey, it's worth financial freedom to me. You can also always rent movies.
Cable. When times are tough, the cable needs to get going. It can get so expensive! If you do need it for the reception, get basic and then rent movies. Buying a great DVD player and renting movies is cheaper than cable in the long run. If you rent rooms in your home like I do, keep the cable, it's a perk for your tenants that are worth paying for.
Take your kids to the bookstore and hang out.
Find free community shows, like Shakespeare in the park or fireworks.
Take the kids on the subway trip -- as far as you can and go explore. In New York, take the train to Coney Island.
In the summer, there is always a local food festival or street fair, usually several Check the local section of your newspaper.Get your kids involved in a community group, like a theatre They develop skills, make friends and have fun.
