Getting Into Flow
When writing there are two modes. One is the hard way—where each sentence comes with a hurculean effort, choosing each word with careful review of your own thoughts. The second, when you're able to just spit things onto the screen in an almost publishable state. I am less good at this than I would like to imagine, as many of the people who caught glaring typos in my writing can attest. However, these flow states are when writing feels the best. The words just come and it doesn't feel like you're hammering your own brain.
These flow states are great no matter the endeavor. I've played epic matches of FPS games where it was just moving and reacting, culminating in a pretty decent score. Compare this to chasing that state, which usually ends in a rage quit. Of course there is the idea that this is the mind shifting into the present, acting on instinct. This is what Zen meditation is training the mind for. This is why you're starting to see people outside Buddhism trying to teach mindfulness and meditation. Trying to harness this flow to create happier and more productive workers, which likely mortifies some Buddhists. But it's rewarding when it feels like whatever your doing is coming straight from your brain, allowing you to fully live in the moment.
