This is such good advice. You replace the switches one at a time, when you realize that it’d be nice to have that thing automated. Trying to do it all at once… that’s eager optimization. It’s overwhelming, and you’ll end up replacing switches that you never use.
The exception is switch panels; my house has a couple 3- and 4- switch panels. When one of those wants automating, I give it a good, hard think about doing all of them while I’m in there.
But the bite-size advice is gold.
It absolutely implies confidence. And his horrified look on his face, well, fuck him. What an absolute shit reaction to your friend saying they’re better in some way than some artificial, professionally made-up fake persona.
No, your waifu isn’t prettier than your IRL friend, and if that were your reaction to your friend’s statement, kicking you to the curb is the least I’d expect from them.
