This is not my best work - I spent way too much time on 90G this week. It so almost works - I have multiple solutions that are one move away from glory. Not even stuck in the same place - I can do any individual part of the puzzle in 90G, but inevitably somewhere will trip me up. Part of me wants to spend more time on this, to crack this nut at any cost. Another, larger, part of me is sick to death of it and wants to just be done with it. I don't know if I want 90 to be possible or not - would I rather have been bashing my head against an unsolvable problem, or have failed to achieve my goal despite many hours of effort. I suspect neither option will bring me peace, though.
