If I purchase new physical goods, I need to make certain I don’t assign them too much meaning. Being able to walk away means I won’t ever get too attached to my belongings, and being unattached to stuff makes our lives tremendously flexible—filled with opportunity.

If I take on a new idea or habit, I do so because it has the potential to benefit my life. New ideas shape the future Me. Same goes for habits. Over time my ideas change, improve, and expand, and my current habits get replaced by new ones that continue to help me grow. Our readiness to jilt ideas or habits means we’re willing to grow—we’re willing to constantly pursue a better version of ourselves.

Crucially, even these exceptions aren’t exceptions. Marriages often end, as do businesses. People get laid off, and passions change over time. Even though we might not be able to walk away from these endeavours in “30 seconds flat,” we can ultimately decamp when these situations no longer serve us.

Everything I allow into my life enters it deliberately. If my home was aflame, there’s nothing I own that can’t be replaced: All photos are scanned. All important files are backed up. And all the stuff has no real meaning. Similarly, I’m prepared to walk away from nearly anything—even the people closest to me—if need be. Doing so safeguards my continued growth and improves my relationships, both of which contribute to a fulfilling, meaningful life.

It was C.S. Lewis who, 50 years ago, eloquently said, “Don’t let your happiness depend on something you may lose.” In today’s material world, a world of fear-fueled clinging, his words seem more apropos than ever.
