I am alternately highly disciplined and highly undisciplined. Sometimes either state can continue for weeks.
Today I'm cranking on a bunch of stuff. But I'm also participating in commenting on blog posts and twitter. Part of that's work, but part isn't. The disciplined approach would be to avoid the not quite work stuff. But damn it's good stuff--hard to pass up :)
Back to it--reading this post reminds me that the post itself has taken me off task.
Dig in :)
