On some days the “black dog” comes barking. Rough days when your ego deflates, and the future looks grim, as when your former supervisor comes to town and wrecks your expectations of a future in this academic business. You feel low, light headed, in a reverie, and unable to move forward, and yet… you put some running shoes, and slide into a lazy sprint. Half an hour later, and you are still going, tireless. And you feel good, so you go a little bit faster. And you go, you keep on going.
