The first resistance to social change is to say it's not necessary.

Change is not merely necessary to life - it is life.

It is not necessary to change. Survival is not mandatory.

It becomes more necessary to see the truth as it is if you realize that the only vehicle for change are these people who have lost their personality.

I am an optimist because I want to change things for the better and I know that blood has to be spilled and disharmony and cruelty are necessary to do that.

What is necessary to change a person is to change his awareness of himself.

People who have car collections - I never understood that. I always thought that was unnecessary. It's not beautiful it's not creative. It's just showing how much money you've got.

Planning cities is a necessary but risky business.

Treaties agreements and organizations to help settle disputes may be necessary but they often favor the interests of business over citizens.

When two men in business always agree one of them is unnecessary.
