For almost every morning over the last couple of months, I've been writing about three pages in my journal first thing in the morning, in n an exercise known to many as morning pages.  One of the side benefits of this exercise is how it helps me to remember dreams from the previous night.  Last night I dreamt about being at a talk by two shaggy hair guys,   Who had invented a new type of spreadsheet tha  for some reason had only two sheets but which could also handle millions of users and billions of variables because the  spreadsheet somehow exploited the fact that all these numbers were not independent of each other.  Great idea but I've no idea of how to implement such a spreadsheet, or how useful such a spreadsheet would actually be in real life.  Nonetheless, dreams are a reminder of how wacky our brains really are.
