Many people have often repeated Bod Dylan's song title from the 60"s "The times they are a changin" and I for one have used it over and over. After reading the article below from Knowledge@Wharton it reflects on just how long we take to realize that something isn't just quite right.
In today's world what we know today from what we learned yesterday will not be that valuable tomorrow. We don't need Moore's Law to tell us that. Look at what you did today and think "will my customer tomorrow want something different?" Are you doing what you do because it is what you know? Do you need to see what you do from the user's perspective? Is your product's value dying off?
Could that be what is happening to the movies? To the music?
This story that I have linked too has so many really good thoughts. Read it slowly.
