Shortly after I moved into my first apartment, I learned my roommate was leaving to take a job in another state in a few weeks. So I rushed out that night and bought new living room furniture.

Sure, I was going to need furniture, as what was in the living room was hers and she was going to be taking it with her. But I didn’t need it that night.

Looking back, the purchase of that couch, love seat and chair had less to do with an immediate need and more to do with an emotional reaction. My friend was leaving. I was losing not just her, but also half the rent money. I was sad and worried. My response: Shop.

I’ve since learned to stop and ask myself some questions, especially before making big purchases: Why am I buying this? Do I really need it? If I wait, will it cost me less?

Determining why I’m spending money can help me decide whether I’m doing it wisely.
