Want to watch a movie? Borrow the DVD from your local library. Want to watch it repeatedly? Buy it off Amazon. Want to read a book? Library. Amazon. AbeBooks. Want to get fit? Go for a hike. Do pushups. Buy a barbell and free weights.
Here's my personal finance plan: Check your bank account daily. Cancel services you don't need. Don't do 30-day trials. Don't sign up for overdraft "protection" at $40 a pop. Use cash if you can't handle plastic, and don't use credit cards. Just don't borrow money, period, if you're not using it to buy a house. Don't let anyone take money out of your checking account but you. If a company screws you, never do business with them again. Pay up front for a year of service and mark when it renews. Write checks before you give out your card numbers.
I know, Stone Age, right? But I like to keep my life simple.
