As the other one replying said, "The Things You Own End Up Owning You." (I dunno why it capitalized those.)
I whittled my belongings down a lot and felt more free. Also in one scene the two men in the back seat say the things they'd regret not having done should they die.
"Paint a self portrait."
"Build a house."
I wanted to build my own house. Always had. I learned construction methods, saved, found land, got a good job nearby... then my health and rest of my fell apart and it took me a decade and bankruptcy to get fixed and get back up on my feet again.
Part of what healed me was meeting the woman who would stay by my side and encouraged me to get surgery.
Now my path isn't building a house but I love the life I've rebuilt. Got a degree, got a iob, and was able to buy my wife the house she had always wanted. Now I work from home with a shitload of pets to keep me company.
