Writing is the same way. Sometimes the words rise up from the depths and just jump right into your damn boat. Everything works and the words pile up all around you, into sentences and paragraphs so many you can't even count. You figured 'em out, these words, and there's a sense that they're going to stay figured out, for always and forever.
The main challenge on those days is deciding which specimens to hold up for the world to see and which to toss back over the side. The implication of the toss-back, of course, is that there are more ideas where those came from. The clear thinking, the concise articulation, the natural rhythm of writing well... you've got all that figured out. Tomorrow will bring another easy boatload. No need to push hard today. Easy come, easy go.
The no-big-deal toss-back is definitely a form of hubris. But on those days where everything is clicking, it's maybe an understandable one.
Holding your ideas up for the world to see is another level of hubris all together. Look at me! I figured it out! Read it! And weep! I alone was able to catch the uncatchable!
Of course in reality all ideas are catchable. Not only that, all the best ideas have already been caught. Look at any piece of writing and you'll see the telltale hook marks from prior writers, prior people who figured out the same things you did; only long before you and better conveyed.

To be honest, I'm not sure where I'm headed here. I noticed some similarities between fishing and writing. That's how it started. I thought I'd be able to shape those similarities into a finely crafted treatise on the feast/famine dualities of fishing and writing and life.
Clearly I was wrong about that. Upon review of the previous 548 words, I see I've been fishing, but not catching. Typing, but not writing. Time to stop casting for the day. Hopefully they'll be biting better tomorrow.
