10 years ago I was unemployed and sleeping when the phone rang. My friend Dan called and said a plane flew into the World Trade Center. I went back to sleep for a minute until my brain digested what he had said. I turned on the TV and spent the day watching in horror as that day's events unfolded. I consider this the first moment in my life that I remember when something "significant" occured in history. It still stings, even ten years later.
