The process of panning for gold shares many similarities to editing / rewriting.
How? I'm glad you asked.
Gold panning involves a number of steps with the first being the use of classifier / sifter screens to separate gold from dirt, gravel and other materials, though during this process you can also find gemstones. Of course, there's more to the process, though it's a lot of repetition with the end goal finding gold.
How often have you heard that "writing is rewriting?"
Does it cause you to cringe and feel, ugh, rewriting, that doesn't sound like fun.
