I am curious about the origin of this quotation:
If you love something, set it free...
if it comes back, it's yours....
if it doesn't, it never was.

I suspect that this is one of those ubiquitous quotes whose true
source may never be found. Attributions are wide and varied.

I know the quote is at least four decades old; it appeared on a poster
that was popular during my college days in the 1960s, attributed to
"Author Anonymous." That guy sure wrote a lot of stuff. ;-)

There are many variants. Here's my favorite:

"If you love something, set it free. If it comes back to you, it is
yours... If it doesn't, it was never meant to be. But, if it just sits
in your living room, messes up your stuff, watches your TV, eats your
food, takes your money, and doesn't appear to realize that you've set
it free... chances are, you either married it or gave birth to it."
