Is there any reason to change my address?

I’m moving out of my parents’ house for the first time by the first of the year. I wasn’t planning on changing my address with the DMV, school, post office, or anywhere else really. I’ll only be 15 minutes from home, so I can easily pick up my mail from home once a week. Is there any reason I would need to change my address?

My plan was to wait until I graduated from college (2 years) or get married, unless something else comes up. Any thoughts?
