Mindfulness is a buzz word you will hear and find in many publications today.

Mindfulness is a state of active, open attention on the present. When you’re mindful, you observe your thoughts and feelings from a distance, without judging them good or bad. Instead of letting your life pass you by, mindfulness means living in the moment and awakening to experience. (Psychology Today )

But the concept is a very old one. The Greek philosophers spoke about it extensively.

“Confine yourself to the present.” ― Marcus Aurelius, Meditations

Marcus Aurelius was Roman Emperor from 161 to 180. He was the last of the Five Good Emperors, and is also considered one of the most important Stoic philosophers.
