Great design makes difficult choices look obvious afterward.

The mark of good design is that afterward you cannot imagine the alternative. The handle is where your hand goes, the button is where you looked. All of the difficulty was absorbed upstream by someone who considered many worse arrangements and left no trace of the ones they rejected.

That invisibility is worth knowing when you evaluate your own work. If it now looks obvious, that may be evidence you did it well rather than that it was easy. Do not let the absence of visible effort convince you nothing was required.
