Thoughts on this economic situation

I hear people complaining all around me about the current economic situation. They act like they have lost so much money and the world is about to end. I was feeling pretty similar earlier today until I talked to my friend kyle. He pointed out that unless you need that money RIGHT NOW, then you haven't really lost anything. You haven't lost any money until you sell, and until you do that its still purely an investment. The economy will eventually recover, and this will soon be just another blip on the radar of ups and downs in Dow Jones's history. Calm down people, you haven't lost any money and the economy will recover!
