People who change their mind a lot

People who were right a lot of the time were often people who changed their minds 37 Signals

Came across this the other day and got to thinking about it after seeing the Steve Jobs book sitting on my bookshelf. One of Steve's many criticisms was that he often changed his mind from day to day. Especially on things that he may have totally trashed the day before. Quite interesting that Bezos points this out. I wonder what he is like from day to day.
