from good to great

I've been reading the book From Good to Great by Jim Collins. Like most popular informative books. The content often feel obvious. Yet it strikes me that we often overlook or under practice the values and work ethics given in these books. In one of the chapters I read this line:

"Greatness is not a function of circumstance. Greatness, it turns out is largely a matter of conscious choices." --Jim Collins

I'm reminded of Malcom Gladwell's ten thousand hours of practice. Its true. Greatness is evidence of making proper decisions, and long hours of obsession and practice.  Eventually you'll go from one whom appreciates to one who's a connoisseur. Are you good or great?
