On the "Input" part of the cycle, I plow my way through books, go out exploring new places and spend perhaps a little too much time on the Internet. I am ravenous for new sensations and new experiences. On the "Output" part of the cycle, I fill pages upon pages, scribble my attempts at artwork and find myself overflowing with ideas, though I may also want to retreat to more stable routines instead of taking in anything else.
The problem with the "Input" cycle is that the words don't come easily, even if I need to produce them. (But I can catch up on my reading like crazy, let me tell ya.)
Every indication is that I'm currently in an "Input" cycle. Instead of beating myself up for it, I figure I'll just stuff myself until I'm satiated and see if that helps any.
