Accept the present moment without judgement.
I have lived with several Zen masters -- all of them cats.
You will enjoy any activity in which you are fully present.
Many things in your life matter, but only one thing matters absolutely.. It is finding the essence of who you are.
The pas has no power to stop you from being present now. Only your grievance about the past can do that.
Ultimately, every great endeavor consists of many little steps.
