Joao, that's a bit below the belt.
Actually, therein lies the problem. The referees asked for just one experiment, but I'm not sure that I can get it to work. And on this one experiment/paper, my career stands or falls (as summarized a bit more optimistically here
It's amazing how up and down I go. I used to be more even-tempered and philosophical about the vagaries of science, but as the months dwindle and the End is nearer and nearer, I find I've lost my serenity. There is only a very thin membrane between me and the depths of despair. Yes, as nnyhav points out, my unrequited love is one of the things that keeps me coming in to work day after day, but sometimes I am so close to walking out and never coming back that it scares me. The other thing that keeps me in place on those days is sheer practicality: a mortgage that has to be paid, that leaves no room for dramatic gestures or flouncings out of the lab.
