Knitting's version of the waiting bus syndrome

Are you familiar with the waiting bus syndrome - where you wait and wait and wait for a bus that never comes because you're afraid that the minute you leave, the bus will come? And the more you wait, the more you're reluctant to leave, having sunk in a certain amount of time already waiting?

I think I encountered knitting's version of the waiting bus syndrome this weekend. I had finished 3/4 of the back of a tank when I realized that an element I had incorporated into it was too narrow to really be visible. But since I was already 3/4 of the way through, I pushed the doubts out of mind and soldiered on. The more I worked on it, though, the more reluctant I was to scrap it and start over. I reached 1/4 of the way up the front before I finally succumbed to the niggling doubts and ripped everything out. Back to square one. Ugh.

But I think ultimately it was the right thing to do.
