A Quote by Irene Joliot-Curie

The time necessary for the disappearance of half the atoms, called the half-life, is a fundamental characteristic of each radio-element; according to the substance, the value of the half-life varies between a fraction of a second and millions of years.

I believe the second half of one's life is meant to be better than the first half. The first half is finding out how you do it. And the second half is enjoying it.

Frances Lear

Our life is half natural and half technological. Half-and-half is good. You cannot deny that high-tech is progress. We need it for jobs. Yet if you make only high-tech, you make war. So we must have a strong human element to keep modesty and natural life.

Nam June Paik

It can be set down as a broad, general principle that we cannot indulge in idleness and abundance during both the first and second half of our life. Study, application, industry, enthusiasm while we are young usually enable us to enjoy life when we grow older. But unless we toil and strive and earn all we can in the first half, the second half of our life is liable to bring disappointment, discomfort, distress. The time to put forth effort is when we are most able to do it, namely, in the years of our greatest strength. The law of compensation hasn't ceased to function.

B. C. Forbes

The essential characteristic of the first half of the twentieth century is the growing weakness, and almost the disappearance, of the idea of value.

Simone Weil

A tree there is that from its topmost bough Is half all glittering flame and half all green Abounding foliage moistened with the dew; And half is half and yet is all the scene; And half and half consume what they renew.

William Butler Yeats

I always thought that I would spend the first half of my life making money so I can spend the second half of my life giving it all away. And one of the defining moments of my life was when I realized that I could do both at the same time with TOMS.

Blake Mycoskie

And yet, and yet, in these our ghostly lives, Half night, half day, half sleeping, half awake, How if our waking life, like that of sleep, Be all a dream in that eternal life To which we wake not till we sleep in death

Pedro Calderon de la Barca

I spent the first half of my life making money and the second half of my life giving it away to do the most good and the least harm.

Andrew Carnegie

Lips half-willing in a doorway. Lips half-singing at a window. Eyes half-dreaming in the walls. Feet half-dancing in a kitchen. Even the clocks half-yawn the hours And the farmers make half-answers.

Carl Sandburg

Life seemed to be an educator's practical joke in which you spent the first half learning and the second half learning that everything you learned in the first half was wrong.
