So this is really great news long-term, really bad news short-term.
I'm writing a chapter for my thesis, that I expected to be only 15 pages. It has five sections.
Writing the first section now....it's not even done and it is currently 10 pages. THE FIRST SECTION. OF FIVE! So the bad news is, I have a LOT of work ahead of me because it seems I am gravely underestimating how many pages I need to do a good job. The great news is, when my balls have been thoroughly busted, my thesis is going to be long and sexy and detailed and I'll look smart. My supervisor said I wasn't being detailed enough, so maybe this is a sign I am on the right track.
Another piece of good news is that I am SUPER into it. I finally found the flow for writing this, so it's long but not tiring. It's nice to enjoy writing again, I have been missing that for so long.
