I pretty much don't delete any emails or voicemails or messages from people I know. It's amazing the amount of stuff I can find from 10 or 15 years ago. It really doesn't take up that much space. I honestly don't know why people get so obsessed about deleting messages and stuff. One of the interesting things about listening to really old messages is that I notice I may get something different out of it now than I did 15 years ago. It's hard to explain, but whatever the person says might tell me something I didn't think of back then, but I think of now. It's super interesting.
