Looks like us 'fixers' got it from our dads. Mine was a real inventor.
Remember how the downspouts on homes used to be round? My dad invented a machine that made the square stuff when others were saying it was too complicated. lol Took him the better part of a year to figure it out and then build the machine to do it, but he succeeded. I used to play in the scraps of sheet metal at the shop and the drill shavings while he worked on that and other inventions.
He also invented the "pallet notcher" and then refused to sue the thief because he was a witness and did not believe in taking people to court.
If he had been a good businessman in addition to an inventor/fixer, I'd be an heiress... lol
