When I talk about happiness, envision yourself at the ripe age of 85, comfortably seated on that metaphorical porch, reflecting upon your life. You’re thinking, ‘Good heavens, I’ve genuinely led a fulfilling life. I’ve established a loving family, spent my life with an extraordinary partner, and devoted myself to a profession that’s injected an immense sense of purpose into my existence. I have minimal regrets and have maintained a light-hearted, playful approach to life.’ This, to me, is what I would categorise as a profound sense of existential happiness.
