Living in the moment is the key concept in mindfullness(i think). Not worrying about the past and anxious about the future we have to feel the moment that we are living now.
Thats the reason, experts in this mindfulness programme will suggest to do meditation for atleast 10min a day or listen to pleasant sounds for sometime daily.
Paying gratitude is also a part of mindfullness. A simple logic, when we are thankful to someone we dont have complaints about them and thus no worries.
