Double the work or double the fun

Today's PhD comic is just where I'm at, after my supervisor commented two weeks ago that progress seemed to be slow. So:

• I'm thick, or
  
• I'm wading through research sludge, or
  
• I'm doing the wrong things, or
  
• I'm not doing enough things.

I am doing enough PhD work. Like fellow PhD blogger, Minh, here, I think and talk about my PhD so I'm well not happy to progress slowly. I want to submit this year.

So what do I do? Double the hours? Do double the wrong things?
