When is it time to give up?

Was back at Backerstrasse. Had a solid session with some overlap with Niki. We tried this one move some 10-20 times (may be another 20-25 times on tuesday). The move didnt look very difficult, and it was gentle on the fingers but still it was just not happening. After much grunting and cursing, I finally got it clean -- it really really felt good. We went to Alt Wien for a quick celebration.
