This is the message of your life and my life - it’s that nothing lasts. Heraclitus said it: Panta Rhei. All flows, nothing lasts. Not your enemies, not your fortune, not who you sleep with at night, not the books, not the house in Saint-Tropez, not even the children - nothing lasts. To the degree that you avert your gaze from this truth, you build the potential for pain into your life. Everything is this act of embracing the present moment, the felt presence of experience, and then moving on to the next felt moment of experience. It’s literally psychological nomadism is what it is.
