You should read books.  Many books from different fields to get a broad scope of what others are seeing, doing & thinking.  Then apply their lessons to your business.  Some of the smartest people read all the time.  It is an exercise in continuous learning.  I once heard a story about William G. McGowan, one of the people who helped lead MCI and the breakup of the old AT&T.  When he flew, he would carry a stack of books with him to read.  So, even toughs of us who have made it continue to read.

Two great books which I just finished and highly recommend are:
“Copy This” by Paul Orfalea, the person who founded & grew Kinko’s and
“Leading For Growth” by Ray Davis, the CEO & President of Umpqua Bank.

I am sure I will be sharing many of their stories here, in the meantime… read!
