There was an article in Salon about this familiar subject (http://www.salon.com/books/laura_miller/2011/03/21/curing_writers_block).
I've never suffered from this phantom ailment. I may be an introvert, but have never been at a loss for something to write about. There are too many diverse thoughts floating through my pea-sized brain. Of course, most of them are completely stupid and the resulting prose borders on worthless--mediocre, at best--but I have never felt "blocked".
Also, I have no fear of making a fool of myself (which should be fairly obvious to even the chance or casual reader of this fare). But, foolishness, like beauty, is in the eye of the beholder, so I have fun putting pen to paper...and then fingers to keyboard. I write for me; anyone that wishes to jump on for the ride is welcome.
This is not unlike my attempts to learn languages. I pick up a few words and a bit of grammar and then let loose on the local population. It goes without saying that this is not pretty. I can tell from facial expression that I have made no sense (few try to figure by interpolation or inference what I could be saying), but I have found that most appreciate the effort. Too many Americans and Brits expect the world to speak English and make no effort to learn another language. That is arrogance, laziness, or fear of making a fool of themselves. As with writing, it's the effort that makes it fun.
