Why oh why, when I have almost achieved completion of a large task on my roll over 'to do' list, I cannot find the last little notch to finish it off.

I can clearly see what is missing; can I lay my hands on what is missing, no! If I could just experience a useful brainwave, it could resolve everything. The job could be at an end and I would, with a flourish of my pen, cross it off the list.

Urrrgh >:XX
