The real voyage of discovery is not seeking new landscapes, but having new eyes. (Proust)
Here are two good pieces of advice:
Make every word Tell. (E.B. White)
The most valuable piece of equipment in the darkroom is the wastebasket. (Ansel Adams)
Both speak to importance of brevity and simplicity in art.
Here's a sample from a forthcoming book on PNW Geology: Ultimately, life depends upon geology. Our bodies, our lives, are the once and future stuff of dinosaurs, of TRex or Stegosaurus, or Velociraptor. Their phosphorous, iron, calcium, and carbon, their very ancient lives are in our bones. We are also the stuff of Permian Lystrosaurus, survivor of the greatest extinction. We share carbon molecules with the great ferny forests of the Carboniferous, and the bug-eyed, multi-legged marine life of the Burgess shale. And in this kinship with the past, we also bear a link to, and a responsibility for, the future. Like it or not, we are investing every molecular scrap in planetary destiny.
