“Plumbing??”
Sure...learning that is like getting a raise of several thousand dollars per year (same with electrical, AC, and auto repair). There’s a reason I live in a (big) house that I’m about to pay off, along with cars that I bought with cash. The reason being that I NEVER have to pay THE MAN to work on my house and only on very rare occasions do I pay THE MAN to work on my cars (and that’s typically tire changeouts and wheel alignments).
Pay me now or Pay me later. :)
