Kyle Baxter with a lesson almost every company needs to learn:

For a business to be successful in the long-term, they must show no devotion to their current products. They must be willing to throw them out at any moment and start over. Their eyes should not be focused on their current profitability; rather, they should be dead-set on where things are going in their industry, what opportunities there are for them as a result, and even how they can apply their core competencies to new areas.
