My father was a physician who enjoyed home improvement projects. He bought the best tools, but unfortunately, he had neither the time or the knowledge to use them. He would take his ideas to a contractor or fabricator and let them do all the work. Smart man.
Yeah my dad was an engineer and did everything by himself. He can do it all. Me, not so much.
Back when I was poorer and had time without kids I would tackle stuff myself - patching walls, changing seats/springs on plumbing, simple wood shelves.
I just don't have the time and I want better quality than what I can produce now. I like to brainstorm with the pros and then let them execute.
