You won't know this name, but football coach Mike Leach was being interviewed by Jeremy Schaff (both are highly respected) as they walked from his home to his office, about a 20 minute walk. Schaff asked Leach what he wanted his obituary to say. Leaches' answer was priceless:
"What do I care? I'm dead."
From a man who actually left a legacy :)
I think that there are people who are trying to "live in the moment" but all they are really worried about, is what they are going to be remembered for. I am not sure if it is future thinking, or future past thinking :)
