Variant: It is not the years in your life but the life in your years that counts.

Context: All progress has resulted from people who took unpopular positions. All change is the result of a change in the contemporary state of mind. Don't be afraid of being out of tune with your environment, and above all pray God that you are not afraid to live, to live hard and fast. To my way of thinking it is not the years in your life but the life in your years that count in the long run. You'll have more fun, you'll do more and you'll get more, you'll give more satisfaction the more you know, the more you have worked, and the more you have lived. For yours is a great adventure at a stirring time in the annals of men.

Context: Lenin is said to have declared that the best way to destroy the capitalist system was to debauch the currency. By a continuing process of inflation, governments can confiscate, secretly and unobserved, an important part of the wealth of their citizens. By this method they not only confiscate, but they confiscate arbitrarily; and, while the process impoverishes many, it actually enriches some. The sight of this arbitrary rearrangement of riches strikes not only at security, but at confidence in the equity of the existing distribution of wealth. Those to whom the system brings windfalls, beyond their deserts and even beyond their expectations or desires, become 'profiteers,' who are the object of the hatred of the bourgeoisie, whom the inflationism has impoverished, not less than of the proletariat. As the inflation proceeds and the real value of the currency fluctuates wildly from month to month, all permanent relations between debtors and creditors, which form the ultimate foundation of capitalism, become so utterly disordered as to be almost meaningless; and the process of wealth-getting degenerates into a gamble and a lottery.
Lenin was certainly right. There is no subtler, no surer means of overturning the existing basis of society than to debauch the currency. The process engages all the hidden forces of economic law on the side of destruction, and does it in a manner which not one man in a million is able to diagnose.
