You've already paid for it, but you still spend for it. How many things that you've paid for are you not taking advantage of? Your municipal taxes heavily subsidize:
- Garbage collection
- Libraries
- Recreation facilities
Why are you paying for someone else to use these while at the same time you spend again buying books to read them once, getting companies to take your extra garbage, or paying ridiculous amounts for gym memberships?
Use what you've already paid for and you'll both save money, be more active, and learn more about where you live.
