I'm going through one of those periods when the well it empty: I can't seem to come up with new ideas. Or at least any ideas worth sharing. This is part of the rhythm of the creative life. I've been doing this long enough that times like this no longer make me panic. I just take it as a sign I need to withdraw into myself a bit more, be quiet and wait. And trust that the muse will smile on me again. Luckily, we've had a bit of nice weather lately which means I've been able to get out for some long walks. Walking acts like a vitamin on my creativity. So, if you are wondering where I am, I'm probably out walking in the half-melted snow, daydreaming.
Hope the ideas are flowing at your desk, though!
