I have been having trouble with the two dissertation chapters I'm writing right now. At times I feel like I'm on a never-ending treadmill. The chapters are basically written; the problem is that I'm at the 'debugging' stage, where it always takes forever to make insignificant progress. It leaves me a bit dazed sometimes. Yesterday, after finishing up (well, almost finishing up) one of the chapters, I went home and almost brushed my teeth with sunscreen.
Today I have to debug the other chapter, the one that needs more work. Joy!
