Marcus Aurelius had the quote "Confine yourself to the present". He was one of the most respected roman emperors, and a famous stoic. Today living the present is associated with reckless living but for the old philosophies it was about questioning every day "what can I do today to improve myself as a human being?"
Because we only care about the short term. The very short term.
It's a great paradox that many philosophies tell us to only care about the present moment ("seize the day!") when in fact many if not all of our problems come from that exact behavior.
What we want, we want it now, and if a price will have to be paid in the future, whatever the actual amount, we regard it as zero. But we're wrong.
