This went over my head at first but it might not go over yours. I had a sponsor who said that it was important to live in and appreciate, and cherish the present moment because it's soon to be your past whether you choose to live in it or not.
Took a long time for me to wrap my head around that one but now I can sure appreciate it. That's how I stay in the now (as best as I can - it's not always easy).
Put the "stay" in "Namaste".
