Anything you cannot relinquish when it has outlived its usefulness possesses you, and in this materialistic age a great many of us are possessed by our possessions
Peace Pilgrim
A vote is like a rifle; its usefulness depends upon the character of the user
Theodore Roosevelt
To waste, to destroy, our natural resources, to skin and exhaust the land instead of using it so as to increase its usefulness, will result in undermining in the days of our children the very prosperity which we ought by right to hand down to them amplified...
Theodore Roosevelt
Now is the accepted time, not tomorrow, not some more convenient season. It is today that our best work can be done and not some future day or future year. It is today that we fit ourselves for the greater usefulness of tomorrow. Today is the seed time, now are the hours of work, and tomorrow comes the harvest and the playtime
W. E. B. Du Bois
Thousands of men breathe, move, and live; pass off the stage of life and are heard of no more. Why? They did not a particle of good in the world; and none were blest by them, none could point to them as the instrument of their redemption; not a line they wrote, not a word they spoke, could be recalled, and so they perished--their light went out in darkness, and they were not remembered more than the insects of yesterday. Will you thus live and die, O man immortal? Live for something
Thomas Chalmers
How often do we sigh for opportunities of doing good, whilst we neglect the openings of Providence in little things, which would frequently lead to the accomplishment of most important usefulness! Dr. Johnson used to say, "He who waits to do a great deal of good at once will never do any." Good is done by degrees. However small in proportion the benefits which follow individual attempts to do good, a great deal may thus be accomplished by perseverance, even in the midst of discouragements and disappointments
George Crabbe
Have I done anything for society? I have then done more for myself. Let that truth be always present to thy mind, and work without cessation
William Gilmore Simms
All the good things of the world are no further good to us than as they are of use, and of all we may heap we enjoy only as much as we can use, and no more
Daniel Defoe
We must make automatic and habitual, as early as possible, as many useful actions as we can... . The more of the details of our daily life we can hand over to the effortless custody of automatism, the ore our higher powers of mind will be set free for their own proper work
William James
Everyone knows the usefulness of the useful, but no one knows the usefulness of the useless
Chuang-tzu
It is not paradox to say that in our most theoretical moods we may be nearest to our most practical applications
Alfred North Whitehead
