You don't want to be near me when I've been out of the studio for more than a week. I transform into an irritable, cranky wreck of a human being. I don't know why this is. And I've heard this is the case with other creative types.
Maybe it's a signal our subconscious sends our way, reminding us there's something that needs attention. And in order to right the ship, in order to find our equilibria, we need to face down whatever it is we're avoiding.
It seems that the world conspires against us, when it comes to doing our most important work. It throws an endless assortment of must-see-television, cheap calories, and other justifiably "important" distractions right at us.
But maybe the world isn't the problem.
It's so much easier to allow yourself to be distracted than it is to face the empty page or the half-finished project. Just get yourself into your studio (or workspace, or coffee shop... wherever it is you get your work done). Sign yourself out of your email, Twitter, Facebook accounts. And just sit.
See what happens.
