I mean, most idioms are silly if you take them at face value.

To me, “easier said than done” is a response to an unrealistic idea that carries the meaning of “I don’t think that’ll work”/“that’s too much”/"etc.

If I told a friend “hey let’s make spaghetti for dinner” and they replied “easier said than done” I’d be like “…okay, you’re technically correct, but I want spaghetti so I’m gonna do that anyways”

But if I told a friend “hey let’s solve world hunger today” and they replied “easier said than done” I’d be like “yeah, I know…maybe we can go help out at a soup kitchen?”

I actually had a similar experience that I can speak to: I reached a point of saturation, I guess you could call it. I needed time to process and integrate everything I’d already read, smooshing more ideas into my brain wouldn’t have done any good.

So I set it down and haven’t gotten back around to finishing.
