Ask yourself these simple questions:
Do I need it?
How many do I already have?
How much will I use it?
How long will it last?
Could I borrow it from a friend or family member?
Am I able to clean and/or maintain it myself?
Will I be able to repair it?
Am I willing to?
Have I researched it to get the best quality for the best price?
How will I dispose of it when I'm done using it?
Are the resources that went into it renewable or nonrenewable?
Is it made from recycled materials, and is it recyclable?
