Your post reminded me of my dad.
We had a neighbor that ran a lot of cattle, we had around 100 head.  The corn we grew that was worth about 93¢ was turned into $2 or $3 corn by feeding those cattle.  
(we had hogs too)
Years later I asked dad, why didn't you buy more cattle and buy corn to feed them.  You'd have made a lot of money.  Dad said, "I had enough."
For dad, a clean farmstead, painted buildings, and decent machinery was enough.
