These hoards of wealth you can unlock at will. [ Wordsworth ]

He that hoards up money takes pains for other men. [ Proverb ]

Charity gives itself rich; covetousness hoards itself poor. [ German Proverb ]

Genius is only as rich as it is generous. If it hoards, it impoverishes itself. What the banker sighs for, the meanest clown may have leisure and a quiet mind. [ Henry D. Thoreau ]

Do you wish to become rich? You may become rich, that is, if you desire it in no half way, but thoroughly. A miser sacrifices all to his single passion; hoards farthings and dies possessed of wealth. Do you wish to master any science or accomplishment? Give yourself to it and it lies beneath your feet. Time and pains will do anything. This world is given as the prize for the men in earnest; and that which is true of this world is truer still of the world to come. [ F. W. Robertson ]
