Here is what Andy Grove said in his speech last Spring to the Society for Neuroscience:

The Holy Grail would be a biological measurement of progression that is objective, repeatable and rock solid. We don't have that. Partly we don't have that because it's complicated. Partly we don’t have that because in my opinion we don't work hard enough in proportion to the complication of the task.

and his metaphoric reference to the “gold nugget” :

The most important characteristic of failure is that it is a golden nugget, something that one should polish, put under a magnifying glass, analyzed --because we don't know what you're going to find when you take the dirt off.

I am working on an OpEd or letter to the Editor or something – I cannot just ignore this opportunity! I lucked out on getting a letter published in the WSJ last time – this one will be more difficult.
