Directed procrastination works for me too. I usually hate admin type of work; sorting out my room, doing the laundry, responding in social media (yes, that counts too..)
But when I hit the inertia part of the productivity cycle, this saves me. It's always better to do something than just being stuck. And while I mechanically do those tasks, my head also gets in order, I start dreaming and slowly, I'm on the roll again.
When the right time comes, I slide back into the 'real' work. I can't quite regret for 'wasting' that time, because usually the reward is a new perspective, and the ideas that come with it.
Shrugs, we're not machines.
