There is a story about a party given by a billionaire that novelists Kurt Vonnegut and Joseph Heller attended. This billionaire threw extravagant Gatsby-esque parties and having illustrious members of the arts was part of the attraction of these galas. Vonnegut turned to Heller at one point and said something along the lines of "Hey Joe, do you realize that our host made more money yesterday than Catch-22 made in its entire history?"
Heller replied "yes, Kurt, but I have something that he can never have."
"What on earth could that be, Joe?" Vonnegut asked.
Heller replied "The knowledge that I’ve got enough".
What is enough? Appreciating ‘enough’ is another way of feeling contentment. The question is how do we attain contentment? Contentment is not something we can someday achieve with study and work. It is not like a college degree. Contentment is knowing that the future has not happened, the past is just a dream, and we only have the now. Once we can appreciate the now, we can realize that everything we need is what we have now.
Meditation and mindfulness allow us to stay present and focus on the moment. It helps us realize our place and fills us with calmness and tranquility.
That is enough.
