Found that using a flexible sanding sponge made all the difference in tight corners. @ellis.leo has a point about waves, but if you keep the sponge flat and use light passes, you can avoid those spots. I worked on a cabinet door edge last week where the router left a rough patch. Just took my time and followed the grain, and it came out smooth without any marks. Isn't it satisfying when you get it right?

I nearly spat out my coffee over that yogurt swap story. Jason Henderson's holy text analogy is too real.

I read about Picasso's Blue Period where he only used blue shades for years. That limit pushed him to explore mood and form in really deep ways. It's like what you said about two colors making you focus on shape and layout. Limits can spark new ideas because you have to solve problems differently. Totally agree that limits are a creative tool, not a barrier!
