Even if you're improvising the fact that beforehand you know certain things will work helps you make those improvisations successful. It really helps to have a certain amount of knowledge about musical structure.

It is becoming clear that the old platitudes can no longer be maintained and that if we wish to improve our morals we must first improve our knowledge.

The improvement of understanding is for two ends: first our own increase of knowledge secondly to enable us to deliver that knowledge to others.

A jazz musician can improvise based on his knowledge of music. He understands how things go together. For a chef once you have that basis that's when cuisine is truly exciting.

Checking the results of a decision against its expectations shows executives what their strengths are where they need to improve and where they lack knowledge or information.

Knowledge has to be improved challenged and increased constantly or it vanishes.

I certainly believe that improving our intelligence is of important national interest.

I want to improve TSA's counterterrorism focus through intelligence and cutting edge technology support the TSA workforce and strengthen the agency's relationships with stakeholders and the traveling public. All of these priorities are interconnected and are vital to TSA's mission - and I would say all of our collective mission.

Intelligence is our first line of defense against terrorism and we must improve the collection capabilities and analysis of intelligence to protect the security of the United States and its allies.

But every time our ability to access information and to communicate it to others is improved in some sense we have achieved an increase over natural intelligence.
