I have breakthroughs from time to time as well and they can set off all kinds of stuff. I'll be sitting there and a single thought will crash through what I thought I knew and effectively force me to re-evaluate what I thought I knew. But usually it helps a little thought the intensity can be pretty hectic.
When it happens, I think of the mother and baby baboons in africa - where the baby clings to his mothers underbelly as she crashes through the underbrush and the baby has to hang on for dear life or get knocked off by whipping branches. I think the thing I try hang on to most stubbornly when its happening is that I am going somewhere. And that anywhere is better than here. Thats the consolation prize at the bottom of the barrel.
