Think ninja warriors without the gear.
Think Harrison Owen, of Open Space Technology fame, and his "one thing less to do" meme. As in 1) meditate, 2) open the space for others, 3) take a nap.
Think Edward de Bono's "Simplicity" book, way too complicated if you ask me, but with condensed messages every other page. (So why exactly did he write the non-condensed versions? Hah, I don't know.)
Think Tarzan, with his Hollywood-appropriate visible underware.
Think PMI, with one minute of looking for positives, one minute of looking for negatives, and a third minute of looking at what's neither but (briefly) captures your attention anyway.
Simple is not easy, quite the contrary.
I select #3 by Amy Smith: "Do the hard work needed to find a simple solution.
As Leonardo da Vinci said, “Simplicity is the ultimate
sophistication”—and it is the key to this type of design work."
Of course, simplicity is only the bottle-neck after you've done all the "absorb and expand" work. "Absorb" as in "look at what's there, include all the factors". And "expand" as in "look at what can be, including what you haven't thought about yet".
Finally, have fun. It's the inner indicator. And look at the effects of your contribution, if there are any, as external validation.
