Customers don't know what they want. There's plenty of good psychology research that shows that people are not able to accurately predict how they would behave in the future. So asking them 'Would you buy my product if it had these three features?' or 'How would you react if we changed our product this way?' is a waste of time. They don't know.

It is I claim nonsense to say that it does not matter which individual man acted as the nucleus for the change. It is precisely this that makes history unpredictable into the future.

I deeply believe that if the Australian Labor Party a party of which I have been a proud member for more than 30 years is to have the best future for our nation then it must change fundamentally its culture and to end the power of faceless men. Australia must be governed by the people not by the factions.

The German philosopher Walter Benjamin had the curious notion that we could change the past. For most of us the past is fixed while the future is open.

The ongoing conflict between us has caused heavy suffering to both peoples. The future can and must be different. Both our peoples are destined to live together side by side on this small piece of land. This reality we cannot change.

The discussion in Washington has changed dramatically. I mean it's no longer a question of should we address entitlements - it's no longer a question of do we need to reduce spending in the future.

Hollywood films have become a cesspool of formula and it's up to us to try to change it... I feel like a preacher! But it's really true. I feel personally responsible for the future of American cinema. Me personally.

I believe it is essential for our planetary future to develop tools that can change the consciousness which has created the crisis that we are in.

I would tell 17-year-olds to be proud of who you are. Don't try to change yourself for others. Focus on school and your future. Boys and friends will come and go just focus on you and your future.

We need the help of other member countries and leaders who like us want to see a change in Europe's direction. That's also my logic when I tell voters that electing me president will not only shape France's future but also initiate change across all of Europe.
